On the new assistant UI on mobile the sidebar UI can be closed only by clicking the "X" button on top right corner of the screen / panel. This has two problems:
The action toggle moves from left to right corner requiring additional seeking and movement when trying to close a menu that was opened from standard-looking "hamburger" menu icon.
The panel does not follow standard swipe action, even though the panel itself was animated on screen from left to right. This gives a mobile user an expectation of being able to close the panel by swipe gesture from right to left.
Figure out if the hamburger menu item could stay in place on mobile UI for triggering both open and close of the side panel. The "X" could be kept as an additional navigation method as it is now. This would make the UI behave more like users have learned to expect from other websites.
Consider adding right-to-left swipe gesture action as an alternative way to close the side panel.
