Finding a specific user's PBI workspaces

Hey all,

I have an associate who left the business I work at, and I need to locate what Power BI workspaces they were in so I can make sure their replacement has access to their PBI reports and dataflows. However, the only method I can find online for determining which workspaces he was in is to use the admin portal to check every workspace. However, due to the size of my company, there are way too many workspaces to check like this. Is there a way for me to check what workspaces a specific user is a member/contributer/viewer/admin of?

Any and all help is appreciated.
