Mulesoft Okta SSO & Groups Query

Hi guys, I am working on setting up SSO using SAML for Mulesoft Application through Okta.
I was successful in doing it. Apart from SSO, we can also map Okta Groups to do Automatic MuleSoft Group Assignment.

As per this doc, scroll down to find "Automatic MuleSoft Group Assignment – Optional"

In Directory I have a group by name MGroup
In Step4,5 - I used condition expression equals and gave MGroup

I followed all the steps multiple times but I am not able to achieve it.
Users will be added to a Role automatically at login, but it is not happening in my case.

Can someone please help me with this.

Hi guys, any help on this is highly appreciated!!
