Unclear how to assign Azure Digital Twins Data Owner role to App Registration.

Hey Microsoft, I think it is unclear in the current docs how to assign roles to an App Registration, and there are pictures that try to show how it should look like but the important part is cut out.

From the docs under heading Create role assignment:
"In this section, you'll create a role assignment for the App Registration on the Azure Digital Twins instance."
It then suggests the Azure Digital Twins Data Owner role.
However, when following the steps in the next to images, there is no option to actually assign this role to the App Registration. It only shows users and managed identities under the member tab, and there is no managed identity option in the App Registration resource itself (like how it works with other resources).

Under Verify role assignments there is another screenshot that just shows the tab Role assigment, but it does not show how that App Registration has been selected.

I am building a React app with MSAL and ADT and getting Unauthorized errors, I think this might be the issue I can nowhere find how to add App Registrations as roles from within other resources than the App Registration itself.

I think this page could be improved by giving some more information about this issue and not cropping the screenshots.

EDIT: Assigning the role through CLI works even though the same action is not possible through UI. Unfortunately I am still getting the same 401 Unauthorized error.
