I have a PowerApps form created for my SharePoint custom list. In that form there is field called contact which is of type person.
If I have field settings as below, my people picker field works fine (this is out of the box control and no customization is done):

Now my actual person field is choosing users from a specific SharePoint Group, not from All users. So when I save the field settings. PowerApps form stopped showing me list of user in the Combobox option.
Can some one let me know if there is any issue in my approach to make this people control work for specific Group of SharePoint?
Update: I have seen that if my SharePoint group has any Azure AD group member then it won't show that group's user in combobox but it will show the direct member of the SharePoint group but not the Azure AD group. So now I am wondering how can I fetch those AD group users into a dropdown.
Thanks in Adavnce!
