Hi,
Trying to integrate a custom UI5 application in the detail screen of a workflow task in My Inbox as per here.
So far I have on the on premise Gateway:

Gone into the on premise ECC and created visualization.

I have made this visualization with various different configurations. No query parameters, add query parameters, leave out openMode, add openMode, try this in transaction ZWFCMD1 and ZWFVISU...
The task displays the standard workflow text instead of my application. I'm not even getting an error.
Can anyone tell me where I'm going wrong with this?
