This is awesome! Thanks a lot!!
I now have a task for assigning all Apple Pay cards to an account of my choice, so I don't have to worry about maestro or MC support at the terminal. For this to always work I first let it Open App 'bunq', wait for my return after login to Shortcuts and then it runs the rest of the tasks. Otherwise the expired login will break the task flow.
Another one to reset my budgets needs to run at the end of each month. I can't find a date trigger that does this without doing all the math myself. So instead I created a repeating task in my Calendar app that appears on the last day of each month. Its reminder will tell me I need to do something and I set the URL field to deeplink "shortcuts://run-shortcut?name=bunq-reset".
Maybe useful to others too.
