According to List members API's documentation:

https://docs.microsoft.com/en-us/graph/api/group-list-members?view=graph-rest-1.0&tabs=http

Currently service principals are not listed as group members due to staged roll-out of service principals on Graph V1.0 endpoint.

This is a feature gap between AD Graph and Microsoft Graph.

As a workaround, you may use az rest to call beta API: https://docs.microsoft.com/en-us/graph/api/group-list-members?view=graph-rest-beta&tabs=http
