When you leave a pocket there should be a DataStore entry showing that you were there recently, with a timestamp. Then if you rejoin the top level server anywhere, you should be prompted (if it is within a few minutes) to ask if you wish to return to that Pocket (e.g. if you quit to fix spatial voice). In the Pockets menu there should also be a "Recent pockets" item.
