Creating a draft in gmail when a google meeting ends

[Jerome_DB]

Hello guys,
So far I’ve made several scenarios but this one is making me losing my hair ! Basically trying to recreate an easy ZAP :

When a google meeting ends
IF i’m the organizer
AND IF a google meet link exists

Create a draft on Gmail.

What’s not working so far :

1. It only finds old meetings.
2. I cannot manage to put my signature in attachment

Thanks for helping !
