Creating plugin - beginners question

I apologize for this likely very dumb question but I can't figure out how to get it solved..
I have cloned the BetterTouchToolPlugins.git and opened it in XCode. At first, when I try to run it the build fails because I have 'No account for team "DAFVSXZ82P"'. Fair enough, I have changed the Team for all the targets to my personal team. After this, build succeeds, plugins get created but nothing is rendered to the touchbar. I would have thought that this let me test my plugin in the sample app instead to copying it to ~/Library/Application Support/BetterTouchTool/Plugins to test it in BTT itself.
Am I misunderstanding anything here? Or do I miss a simple and obvious point?
Any support appreciated!

Ok, found the issue:
I was trying to build the BTTTouchBarPluginSampleCustomView instead of the BetterTouchToolPluginDevelopment.
Once I selected BetterTouchToolPluginDevelopment in Product --> Edit Scheme the buttons were rendered to the touchbar.
