Firebase security rules: Get a document with a space in the documentID - firebase

Question

I am writing firebase security rules, and I am attempting to get a document that may have a space in its documentID.
I have the following snippet which works well when the document does not have a space
function isAdminOfCompany(companyName) {
let company = get(/databases/$(database)/documents/Companies/$(companyName));
return company.data.authorizedUsers[request.auth.uid].access == "ADMIN;
}
Under the collection, "Companies", I have a document called "Test" and another called "Test Company" - Trying to get the document corresponding to "Test" works just fine, but "Test Company" does not seem to work, as the company variable (first line into the function) is equal to null as per the firebase security rules "playground".
My thought is that there is something to do with URL encoding, but replacing the space in a documentID to "%20" or a "+" does not change the result. Perhaps spaces are illegal characters for documentIDs (https://cloud.google.com/firestore/docs/best-practices lists a few best practices)
Any help would be appreciated!
EDIT: As per a few comments, I Will add some additional images/explanations below.
Here is the structure of my database
And here is what fields are present in the user documents
In short, the following snippet reproduces the problem (I am not actually using this, but it demonstrates the issue the same way)
rules_version = '2';
service cloud.firestore {
match /databases/{database}/documents {
match /Users/{user} {
allow update: if findPermission(resource.data.company) == "MASTER"
}
function findPermission(companyName) {
let c = get(path("/databases/" + database + "/documents/Companies/" + companyName));
return c.data.authorizedUsers[request.auth.uid].access;
}
}
}
When I try to update a user called test#email.com (which belongs to company "Test"), the operation is permitted, and everything works exactly as expected.
The issue arises when a user, called test2#email.com, who belongs to company "Test Company" comes along and makes the same request (with authorization email/uid updated in playground, to match what is actually found in the company structure), the request fails. The request fails, since the get() call (line 1 of the function) cannot find the Company document corresponding to "Test Company" - indicated by the variable "c" being null in the screenshot (see below) - IT IS NOT NULL WHEN LOOKING FOR "Test"
Below is a screenshot of the error message, as well as some of the relevant variables when the error occurs

Check to see what type of space just in case it is another non-printable character. You could convert it to Unicode, and check what it might be. However, it is considered bad practice to use spaces in naming variables and data structures. There are so many different types to consider.
| Unicode | HTML | Description | Example |
|---------|--------|--------------------|---------|
| U+0020 | &#32 | Space | [ ] |
| U+00A0 | &#160 | No-Break Space | [ ] |
| U+2000 | &#8192 | En Quad | [ ] |
| U+2001 | &#8193 | Em Quad | [ ] |
| U+2002 | &#8194 | En Space | [ ] |
| U+2003 | &#8195 | Em Space | [ ] |
| U+2004 | &#8196 | Three-Per-Em Space | [ ] |
| U+2005 | &#8197 | Four-Per-Em Space | [ ] |
| U+2006 | &#8198 | Six-Per-Em Space | [ ] |
| U+2007 | &#8199 | Figure Space | [ ] |
| U+2008 | &#8200 | Punctuation Space | [ ] |
| U+2009 | &#8201 | Thin Space | [ ] |
