Question How to disable the Sidebar in calendar view

[Hanni]

Hey there,
I am totally newly operating with wordpress and not fluently english speaking and having a problem with my calender view.
I am testing everything on this page: http://lebe-gelassen-königlich.de
I was using a elementor oceanwp template and on all my pages I have no sidebar.
Now I installed a calender plugin (time.ly bit its the same with other) and there is always this sidebar from the previous elementor template on the right side.
http://lebe-gelassen-königlich.de/calendar/
I do not know how to deactivate it. Could anybody help please?
Thank you
Ines
