How can I import an ets project for the knx app

I have installed the knx app,
but I found only the option to create a single dimmer/switch etc.

How can I import some 100 Knx Group Addresses from an ets project?

Hi Michael,
when you create a new device, there is the possibility to import a ETS project or set the GA manually.

Have fun

I don’t understand how I can do this. I select for example this icon. then it shows me the option of uploading an .knxproj file - which I do. But then it shows me a window where I can add a single item instead of importing all the entries in the knxproj file. (?). I do not want to manually enter hundreds of switches etc. Am I missing something?
