Remove Messenger Snippet

Hello Facebook,

So I was wondering, is there a way to fully remove the chat plugin from a website after going through the whole setup process and having it insert a seemingly elusive snippet that can’t be located anywhere? I don’t mean to remove it anyway by asking this question though having apprehension now in case I may have to in the future, seeing that every concern regarding this has gone cold so far.

I also intend to integrate the chat widget into my other website but at this rate am looking to do it manually by copy-pasting the snippet into footer section, just to be safe from not being able to revert the changes. Am I right in assuming things that way? Please let us know of a definitive way to go about the dis-integration process for the plugin widget so that users may have better experience with this plugin.

Best.
