If you choose to enable shift invitations, this allows the volunteer to accept a shift before they are automatically assigned. Here is how you can set this up.
How to enable shift invitations
Go into the mission
Go to 'Additional settings'
Go to the 'Shifts' section and toggle on 'Volunteers must accept the shifts you assign them'
How to invite a volunteer to a shift
Go to 'Volunteer shifts'
Click on the shift, then 'Volunteers', then 'Manage volunteers'
Select 'Assign volunteers'
Go to the volunteer and select 'Assign shift'
Check the volunteer's status to see if they have confirmed the shift
Once accepted, the status will say 'Assigned'
If declined, the volunteer will no longer appear in the volunteer list for the shift
You will be able to track whether volunteers accept or decline in the mission's activity log
