The problem isn't in Minecraft itself.. it depends on the Android OS "flavor" your manufacturer's using. If you're using Samsung or Google branded device, using Android 8 or later (or even a ChromeOS/Android-x86 based flavor), most likely you'll get a proper right clicking support. If the right click acts as back button, check the right-click behavior option in the Android Mouse Settings that's usually in Language/Input section. Unfortunately though most Chinese-branded devices removed the option to change the right-click behavior, after some research it's most likely intended to promote their gamepads which feels unfortunate to those people who owned these devices.
