How debug a Magento module issue started from frontend

I have a Magento 2.3.3 installed with some modules. There is one module that has been uninstalled before still display on frontend. It looks to me either the module could not be uninstalled completely or I made mistake on identifying the module.

Is there an approach I could trace which part / module contributing a button ( I want to remove ) from the frontend?

Thanks.
