Hello,
Please use setter functions. This will help you identify, where buttons component is used.
Then you can dispatch custom events accordingly.
Hope this will show some light to you.

you have to write button listeners for each module separately and you can attach the listeners to buttons
if buttons are in myButtons component and myButtons component is loaded inside module you can write myButtons.deleteBtn.addlistener(.. inside the module and similarly in other modules

You need a global variables to keep track of current active module. Assume that the current active module is "receipts" and "new" button is clicked, you dispatch an event: "receipts_new_clicked". In main stage, you add an event listener to listen those events.
