Power Virtual Agent auto install to few groups

Hi All,

We have developed the bot in Power Virtual Agent in teams. we have published and downloaded the manifest package and uploaded into Teams Admin Portal.

In Teams admin disabled usage of custom app in Global (Org-wide default)

Here is the requirement we are looking for:

We have Azure security Group. we have allow the this group to use the Teams bot and auto install to their teams.

1. We created a permission policy : PVA Bot Permission Policy to allow specific custom app

2. We created a App Setup policy to install app:  Avion App Setup Policy

While choosing App we selected the Policy created before

3. We created a Group Policy assignment

After doing all this steps I am getting the below error.

Please let me know if I am missing any steps to allow app to auto install and use it for specific group.
