power automate user running flow or modified by not available

(I copied this from another site but these options are not available for me)

I also found these dynamic options on another site and this is not available neither under dynamic content:

Does anyone know how I can retrieve the userid of the person executing the flow? (uploading the file) Thank You before hand.

These are the original actions to get the file being uploaded:

This is the additional step required, adding a "Get File Properties", which then allows you to use the "Created By Email" property. Below it is being stored in a variable called varUserEmail:
