Delete events i have created

Hi Francky,
Some users of my site can create events with this plugin. But they can’t delete their events after create it with this plugin.
I give them access to the backend where they can access only to owned event. They can update it but they can’t delete their event.
This option “delete” doesn’t exist in the menu setting/access/events only modify/update
Is it necessary to be administrator to delete an event or is there a solution for those who have created this event ?
Thanks a lot for your work.
Best regards
