Hello Nino,
After further research, you may indirectly be able to run a Power App from within Warehouse Insight by triggering Warehouse Insight to open up your web browser that contains the Power Ppp.
You would be limited to opening the Power App from a web browser and not directly running the Power App within Warehouse Insight.

Thank you,
