So, we have Amazon Connect Chat and Twilio SMS integrated within our environment. We would like to have in them something like the standard functionality of Quick Text which is allowed only on certain places.

Is it possible to integrate Quick Text somehow with any of these? And if not, what would be the workaround here? 

Since both of these are managed packages, we have tried creating our custom LWC Component which will take by id the Send Message text area, and transfer the shortcut from our component to Amazon Connect or Twillio respectively, but we have hit an issue there also, which is quite wierd. For example, within the console, I am able to access the textarea with query selector and manipulate with it, however when I do the same within the LWC, it returns a proxy object which has the textarea in its Target and i am not able manipulate it. The JSON.stringify(JSON.parse()) trick doesn't work also.
