1. Open the “Edit Channel” page in a modal instead in new page.
  2. Show help icon and tooltip next to each “right”, so user can see what each role is able to do
  3. Button “Save Changes” saves the changes and leads to current page (no dropdown button anymore)
  4. On task page and in feed add a link to the channels, that opens the modal if user has manager rights
  5. If user does not have manager rights show “You need at least manager rights in the organisation to edit this”
