While playing around cards for Power Apps, I noted that the User Power Fx function that is used in Canvas Apps to detect the current user and get some information about it is not supported.
After some investigation, I found that Cards use a new object called Viewer instead.
How to use the Viewer Object
The viewer object has 3 properties that potentially we could use to filter data by the Current User :
- name: it’s the user Display name
- aadObjectId: ID of the user in Azure AD
- id: weirdly this displays the UPN when loading in the Cards player but it displays something that seems like a Teams identifier when sending the Card in Teams, for example: 29:16a03jETMRncoewiNAeiWgBqzzxv-Rx16996NUHRjgNHW8Bb7449q-Y3ku9-s4a3ZE3AR_e0NQiM-6qx2n3vWIw
Filtering data by the display name can be messy as there could be two people with the same name in the tenant, so going with the aadObjectId would be the most precise way.
