Calendar plugin - transfer id by clicking on an event in the calendar

[indiedev84]

I encountered a problem. In the Calendar plugin, there is no way to pass any value from the database that is attached to the calendar, for example, to make a form that opens and receives data by event id.
Perhaps I did not see this method. If so, I ask the community to help me with this.
I also worked with another Kanban plugin, there you can get data from the board.
