use remember me cookie to start authentication

[louisgls]

thank you for all the extensions.
I'm currently using the dynamic idp redirector extension which is great but I would also like the email to be retrieved from the "remember me" cookie if it is set instead of the form.
Do I need to create my own extension or is that already implemented somewhere ?

I have tried different things like the "script" execution in keycloak, I can retrieve the email but I'm not sure what I have to do next to make the extension work. Set the user in the "context" by looking for users with this email ?

Authentication flow could be either :

Username form
Dynamic IDP Redirector

OR

Remember me Cookie
Dynamic IDP Redirector
