Hi @auth029,
Welcome to the Auth0 Community!
Unfortunately, there isn’t an Action flow that can be triggered after a user’s role has been updated. For now, the only flows available in Actions are listed here.
As a workaround I recommend using the Management API Update a user endpoint to update the user’s Roles. And then writing a script to make the HTTP request to propagate the role to the client apps.
I hope this helps!
Thanks,
Rueben
