Create or Edit Mobile App Home Screen

[TALENAJ]

I'm trying to edit the home screen on our mobile app. 

So far I have made it to the Mobile App Builder, selected my scope, and created a function. I see the location I need to add the function in Mobile App Configs but there is not a way to edit the section I need to edit. 

I need to add that function to the main screen on the home tab. I have attached screenshots everything including the function, the location in Mobile App Configs and the launcher screens. 

Looking at my screenshots, I would like to add "Incident" to the "My Items" section however I do not have the "New" option to select Incident. 

I have also included a screenshot of the mobile app as it currently looks, with notations of where I would like to add the function I created. 

Thank you for any help you can provide.
