Confused how to customize meteor verification email - meteor

Question

How do I get the verification link from the default Meteor method into a custom email method I have that uses sendgrid stmp.
here is the meteor verification method that works well on its own and has the link I want:
sendVerificationLink() {
let userId = Meteor.userId();
if ( userId ) {
return Accounts.sendVerificationEmail( userId );
}
},
Here is my custom method that uses sendgrid, everything works except for I cant figure out how to get the link with the custom token:
'signupEmail' (submission) {
this.unblock();
const link = ''
const message = `welcome ${submission.firstname} `
const text = `welcome ${submission.firstname}. Please verify your
account ${link}`
Email.send({
from: "hi#test.com",
to: submission.email,
subject: message,
text: text,
html: text,
});
}

Just in case anyone is looking for this in the future I found an answer on Meteor forums: https://forums.meteor.com/t/how-to-get-verification-link-for-custom-sent-verification-email/22932/2
Basically I added a token record and saved it in the database. Then used the token with the method: Accounts.urls.verifyEmail which created the link to insert in the email.
Here is my final method:
'signupEmail' (submission) {
this.unblock();
let userId = Meteor.userId();
var tokenRecord = {
token: Random.secret(),
address: submission.email,
when: new Date()};
Meteor.users.update(
{_id: userId},
{$push: {'services.email.verificationTokens': tokenRecord}}
);
const verifyEmailUrl = Accounts.urls.verifyEmail(tokenRecord.token);
const message = `welcome ${submission.firstname} `
const text = `welcome ${submission.firstname}. Please verify your account ${verifyEmailUrl}`
Email.send({
from: "hi#test.com",
to: submission.email,
subject: message,
text: text,
html: text,
});
},
