Dividing screen touch interface for multiple options in Bangle JS 2

One way I've done this is to read the position of the users touch point and use if-statements to choose between entries.

Something like:

if (50 < event.y && event.y < 100) { open first entry }
else if (100 <= event.y && event.y < 150) { open second entry }
....

I've done this here in a custom setUI (line 106) starting on line 117.
