title: How to hide certain actions from the Chrome Custom Tab menu (e.g. the bookmark and download buttons)?
body: <p>I'm using a Chrome Custom Tab on my app and I'd like to be able to disable a few buttons that pop up automatically when I launch it to open a Google drive file, namely the button for bookmarking the page and the button for downloading it. I've searched throughout the web with no luck whatsoever.</p>
  
  <p>Below is the image highlighting which buttons exactly I seek to hide in my custom tab. Anyone knows how to achieve this?! Thank you so much in advance.</p>
