Automation and calendar

Hi there! I have three questions.
First - how can I create a calendar view which will show all the events from all my work boards?
Second is about the automations - what form should I use - when I change the status of the item to “confirm” I want automation to create a group in other board with the same name as the item. Automation let me to create a group in other board but asks me to fill in the name of the created group. I want this process to automate and to create a group with same name as item I’ve changed the status already.
Third and last - I have successfully connected with google cal but when I create an event with date it doesnt create an event in goole calendar - what am I doing wrong?
Thanks for your help!
