How do I use the API to open an interface in a new tab?

I’ve written a new interface for my users. I want this to open in a new tab. I cannot find the function(s) responsible for this. Can someone point those out? If the documentation isn’t clear, I would also greatly appreciate knowing the arguments.

I have found a function “menuActionClick(data, evt)” that appears to be how a menu-click opens a new tab, but I’m not entirely convinced. Regardless, I haven’t found what the ‘data’ argument is supposed to be.

Thank you for your help!
