Problem in coding a Welcome Message along with options

Thanks Sir for replying back !

I did edit the default session timeout to 1 minute yet in the RASA X it showed action_session_start only when I started the RASA X despite of showing after every 1 minute of inactivity.

Could you elaborate on How to generate different sender_id values for testing purposes ?
So far I know that I can share the RASA X link with different users for test purpose.

I don’t have log messages to confirm.

Yes, action_session_start is defined in the actions: section of my domain.yml .
I had followed this answer previously.

Please, guide me Sir.
