I want to create an activity app, but there are not many videos or tutorials about the whole process of the coding, I wanted to ask you if someone knows a link to download a template code like one of the internal activity apps from garmin that I could use for my app, or at least a source to learn how to code for garmin, I want to have a layout and a menu in one view like the picture below but I don't know how to do it, please someone help me, thank you
