What button to use on my Samsung remote to control Fire Stick function

[OmenRIP]

My Samsung remote for my QN90A mostly works great when controlling my Fire Tv Stick 4K Max. However, there is one button on the Fire TV remote that I can’t find an equivalent on my Samsung remote - it’s the hamburger or 3-horizontal lines button. 

Has anyone found which button to use on the Samsung remote? Or do I need to buy a universal remote to program this button?

I cant find a fix for this either and threw away the firestick remote!
