I am working with Odoo v14 CE.
With the activity on the chatter panel, when I click on "Mark Done" a pop-up window show. I can enter the feedback. And the feedback is shown in the message on the chatter panel.

However on the form view, when I click on "Mark as Done" there is no popup to provide the feedback, nothing show on the message.

How to enter feedback on the activity form view?

Thank you,
