Hi @Pascal_lecossec ,
Would you like to use the Help Desk sample App in Power Apps?
If so, according to my test, the application package downloaded from here cannot be opened. If you have already created SP list followed the instructions in the doc, you could open the app in Power Apps via:
1\ Find the .msapp file from the package you downloaded, copy and paste to the location you like:
2\ As you have imported the package, the Flow is already in your environment, check for sure in Power Apps portal and turn it on.
3\ In Power Apps portal, find Apps, select "New app", select "Canvas".
4\ Open the .msapp file that you pasted just now:
5\ The app is opened in Power Apps studio now. In Apps OnStart, modify the Admin list to include actual admin accounts:
ClearCollect(AdminList,"Email1","Email2",User().Email);
6\ Remove HelpDeskFlow and HelpDesk connections from the list and add your own SP list HelpDesk as data source via Add data source button, refresh the connection after adding in:
7\ Save the app with a name you preferred.
8\ Copy all formulas of OnVisible MyTicketsScreen, select "Action" on command bar then select Power Automate.
9\ Select the HelpDeskFlow in Flow list, then you will see formulas in OnVisible all be replace by the flow.run action. Paste formulas copied in last step and delete the flow.run part that appears after adding from flow list.
10\ Select edit to modify the HelpDeskFlow in Flow list:
11\ Delete contents in Site Address and List Name, choose your own site and list then select save.
12\ Save and publish the app again.
Steps of modifying connections and Flows are already included in that official doc.
From this moment, you would be able to modify or use the app with no big issue. If you encounter any problem, please feel free to leave it here in the community.
Hope this helps.
