I used this workaround to send a triggered email to new members with a link confirmation, but with the old way, I don’t know if it can help:
wixUsers.emailUser(“xxxxxxxCODE”, userId, { variables: {“CONFERMA”: " https://www.google.it "}} );
It returns a clickable link !
Of course now instead of www.google.it you have to form and place the correct dynamic_user_link
For now it works !
