Retrieve the userid when needed

Dear all,

I would like to generate automatically the AI Builder consumption report https://youtu.be/8l79x8THx6I

and create a new report with "converted" data with Power BI, since in this report, it gives the IDs (environment ID and user ID). For the Environment id i can create a mapping table. For the userid, it is more complicated to me.... how i can retrieve the ID of a user when it is mentioned in the report?

thank you
