Email notification on shared folder and first connection

Hi !

I have recently installed Nextcloud 15.
I plan to create users without password (they will enter it thanks to the “Welcome email”) and share one folder with each one of them.
I’m facing a little problem, when a user opens his mailbox he opens the last received email, the “new shared folder” one, he’s asked to enter username/password however like he doesn’t have entered his password yet the login fails.

Is it possible to reroute the user on the new password page if he logs on for the first ?

Thanks !
