No access to Payment schedules created with "Advanced options"

As a user, after successfully creating a ZapPlanner payment schedule using the default flow (hard-coded to monthly payments), the new schedule IS listed on the ZapPlanner main page. Expected behaviour :-)

As a user, after successfully creating a ZapPlanner payment schedule using the "Advanced options", and closing that tab, I cannot find any way to return to the new schedule in order to cancel it. The newly created schedule is NOT listed. This is probably great if you're the recipient of the sats but not so great if you're the sender!

Opening ZapPlanner should by default, list ALL the existing schedules that have been created so that they can be reviewed, (amended) or cancelled.

Currently, any payment schedule created with the "Advanced options" can't be accessed again, and therefore can't be cancelled, unless the user saves the url of that schedule outside of ZapPlanner/Alby.

Start by reproducing the Advanced options flow, closing the schedule tab, and checking the ZapPlanner main page. Trace how existing payment schedules are loaded and represented, then verify that schedules created through Advanced options are listed and can be cancelled without relying on a saved URL.
