Hi Christian,
Thanks for such a great plugin! I am heavily using it to automate my flows.
I was checking the API to see if there was a date picker component to add to the modal, but did not find any. Then I checked if there was any as part of the app module and nope also.
Finally I realised that the author of the calendar plugin was requested to export the calendar from his plugin here and ended up releasing this repo with the component
I was trying to figure out how to integrate, but my javascript is only enough to make tweaks here and there. Could you evaluate if it is possible to integrate such option to the modals? I could for sure give a try and send a PR later, but if it is not that complicated a dev like you could get it done way faster.
Thanks a lot!
