Hey, I found an answer in other post. The issue is that Hot Reload only reloads the project, but not plugins. Hence, we need to recompile/reload the plugin manually every time.
The solution: Windows/Developer Tools/Modules. Then find your plugin, and hit Recompile button next to it.
My workflow is that I leave this window attached to other windows and I always have my plugin name in the search field.
Best case scenario would be to create editor button and attach it somewhere.
