If you do a backswipe on the left side of Kagi Assistant for Android the menu opens at the same time as the system does back navigation.
I believe this shouldn't happen. If guesture navigation is activated in Android then the app should do things when you do back swipes. Perhaps the hit box for the sidebar could be moved towards the center of the screen for those who want to swipe to open it? Is it possible to check if guesture navigation is activated and make adjustments accordingly?
