Hi @olivierverbe ,
In my example, I used cloud flow to call the desktop flow.
So, if the user clicks the button in sharepoint page, it will trigger the cloud flow and the cloud flow will run the desktop flow.
If you use flow Run URL "ms-powerautomate:/console/flow/run?environmentid=64...", it will run the desktop flow on the user's own PC environment rather than the PC environment which created the desktop flow.
Best Regards,
