Cosmos DB - can't use a property (array) with IN Keyword - azure-cosmosdb

Question

I'm attempting to query for several documents at once, using some properties that were found on the first document, similar to a TSQL left join on property value.
My attempt in CosmosDB:
select c from assets
join ver on c.versions
where c.id = '123' OR c.id IN ver.otherIds
--NOTE: ver.otherIds is an array
The query above results in a syntax error, stating it doesn't understand ver.otherIds. The docs state the syntax to be where c.id in ("123","456"...)
Things I've tried to work around this:
Attempted Custom UDF that takes in the array generates the syntax wanted Ex) ["123,"456"] --> "("123", "456")
Attempted using array_contains(ver.otherIds, c.id)
Attempted sub query approach, which produced a "The cardinality of a scalar subquery result set cannot be greater than one" error:
select value c from c
where array_contains((select ... that produces array), c.id)
None of the above worked.
I can, of course, pull the first asset, then generate a second query to pull the rest, but I'd rather not do that. I can also just de-normalize all the data, but without giving specifics to my scenario, it would end up being a very bad idea.
Any ideas?
Thanks in advance!

You could use your second scenario:ARRAY_CONTAINS.
My sample document:
[
{
"id": "1",
"versions": [
{
"otherIds": [
"1",
"2",
"3"
]
}
]
},
{
"id": "2",
"versions": [
{
"otherIds": [
"1",
"2",
"3"
]
},
{
"otherIds": [
"123",
"2",
"3"
]
}
]
},
{
"id": "123",
"versions": [
{
"otherIds": [
"1",
"2",
"3"
]
},
{
"otherIds": [
"123",
"2",
"3"
]
}
]
}
]
SQL：
SELECT distinct c.id,c.versions FROM c
join ver in c.versions
where c.id="123" or array_contains(ver.otherIds,c.id,false)
ARRAY_CONTAINS function can specify if the match is full or partial.
