Secure embedding externalIdentifier

I was trying to use secure embedding by providing my current user email address in externalIdentifier but it goes and create a new user with the same email address.
When i tried to include the email address in userInfo.email it gives an error saying

    "error": true,
    "message": "Validation error: email must be unique, organizationId must be unique"

May i know correct combination to not create new users.

In additionally i have few metadata i hope this won't be an issue...

And what's the difference between Product experience in Embed user Desktop + mobile ?
Which cost structure apply for Embed user?

Any update on this would be really appreciated....

Hey @tharkana_am!

Passing in an existing users email in the userInfo object should not create a new user, and should update the existing user. Can you share the POST request you are using to generate the embed link?

I've tested this a bit this morning and it seems to be working, so just want to see where the discrepancy might be. Thanks!
