No MENU option on Samsung Galaxy Note 8 for Gmail

[caseb]

I have a Samsung Galaxy Note 8. I have the gmail icon on home-screen. I would like to get to the "add signature." I don't have a menu button for this under settings or anywhere else. It seems my gmail app is via google. I'm not very savvy, but I have searched and searched for the menu/settings for my gmail app/icon. Your help is appreciated.

Go to Gmail, click lines on the side (see the second picture below), scroll all the way down and select Settings - - > see the first picture
