Binding for controller button: home

i am currently searching for the input name of the home buttons from different controllers but i’m not able to find it. There are a lot of special inputs for various controllers but there seems to be no input action for the home buttons (like the xbox “X” in the upper middle of an xbox controller or the steam home button for steam controllers).

Can someone please tell me how this input button is called ?

Thanks a lot!

Still stuck on this issue. Any help is very appreciated.
