Non agent approvers cannot approve event workflows.

Hello, We have followed the guides in creating an approval workflow for our Events Module. The KB article stated that an approver does not need to be an agent and only needs the “Log in” permission. The workflow is working as intended and the approver receives an email. However, once they click on the Approve button and are brought to the event ticket, it does not approve and there is no option to click approve. Nothing appears under the dashboard of the approver as in the KB screenshots. Can anyone assist with making this work correctly?
