I'd like to elaborate a bit on the accepted answer. The Chrome 83 indeed removed the possibility to add custom headers, yet Chrome 86 reverted this functionality under certain strict conditions. See https://developers.google.com/web/android/custom-tabs/headers. Just follow an example from https://github.com/GoogleChrome/android-browser-helper/tree/master/demos/custom-tabs-headers.

TD;DR - you must own both app and website for making it work as the changes in app and The Digital Asset Links protocol file (website address (...)/.well-known/assetlinks.json) are needed.

Be sure to follow the tutorial and example precisely. In my case I stumbled with the one detail - CustomTabsIntent Builder needs a CustomTabsSession object set up.
