Oh dear lord I truly hope not (And judging by your screenshot this is very wrong)
At any rate, go into the Mixer or open the editor mixer strip (SHIFT+E) and select that track. You should see DrumGizmo listed as a plugin on that track and you can double click on it t here to open it’s UI,
Plugins are part of the Mixer (not Editor).
Use the Mixer window (Menu > Window .> MIxer) or as @seablade suggested the Editor-mixer (Menu > View > Show Editor Mixer)
