falied to triggger playbook - Sentinel

Hi, I'm learning how to create playbooks. I'm having trouble with permissions on a playbook - I don't know where the problem is.

From the Sentinel level, I gave access to the entire resource group, and in the Logic App, I also added an identity - Sentinel responder. Where else could I be making a mistake? If anyone is knowledgeable about playbooks, please help me! I am trying to figure this out a few hrs now

PS: I'm looking for someone who can spare me 20 minutes for a call with sharing screen. It would be great for me if someone could take a look at my lab environment and give me some advices. Thank you!
