Buddypress group members can create group events

Hi, thank you for a good plugin.
I’m using Buddypress groups with Events Manager. I have a problem that a group member can’t create group events. This means that if he is a member of a group, his events are not connected to his group as a private one.
Now, only the group administrator can create group events. Is there any option to allow members to add group events without being a group administrator?

Thanks.
