Hi @Rishabh126 ,
Do you want to add a azure ad group as a team in power platform?
Based on your description, I assume that you've created azure ad group.
Then, you need to add a team in your environment and use this group's information.
1)choose your environment, choose settings
2)choose team

3)choose "new", create a new team.


After you creating the team successfully, you could find it here:

Then the member information will be the same as the group.
Please note that:
The list of team members listed in each group team only displays the user members who have accessed the environment. This list doesn’t show all the group members of the Azure AD group.
4)create a new security role that you want to assign to this team
choose "security role" in the settings of the environment.

Please note that, if you create a security role for a team you need to choose Direct User/Basic access level and Team privileges when creating the security role.
5)in the team part, assign this security role to this team.
Here are two docs about it for your reference:

Best regards,
