Enabling target audience field in powerapps

I have created a list and have enabled the target audience setting in the list. For any new item created, I assign a shareoint group or user's in the target audience field. So only the users listed  in the target audience field would be able to see or edit the item in the list.

When I customize the form/ list  using powerapps, am not able to see the target audience data card in the sharepoint datasource. How would I have the target audience field shown in powerapps ?
