I’m using cognito with my software and I would like su support VERP.

I want to register in my software as a different user:

• [email protected]
• [email protected]

I have succesfully created users via admin create user api (self enrollment is disabled in my usecase)

But trying to set a new password I receive this error from cognito api backend:

{
    "code": "InvalidParameterException",
    "name": "InvalidParameterException",
    "message": "2 validation errors detected: Value at 'userAlias' failed to satisfy constraint: Member must satisfy regular expression pattern: [\p{L}\p{M}\p{S}\p{N}\p{P}]+; Value at 'userName' failed to satisfy constraint: Member must satisfy regular expression pattern: [\p{L}\p{M}\p{S}\p{N}\p{P}]+"
}

Is there any way to edit these constraints ?
I have not found anywhere in documentation or configuration references to this.
