Have you tried pressing and holding the back button or enabling the Assistant menu?
When the Assistant menu button is switched on (Settings - Accessibility - Dexterity and interaction), a blue symbol with four white squares appears. If this symbol is pressed, a menu pops up with a selection of available tasks. This includes (on page 2/4) a button called "More options". This is the extra Menu button that should be accessible from a long press of the Back button, but is not available in some apps.
