Would be great to be able to have meetings in ClickUp that externals (CU account optional) can be invited to. A key feature would be remote screen control, eventually using the ClickUp App / Browser Add-On. You should be able to set people "Enable pointering" so that they can not remote-control, but pointer on the active screen or show their mouse pointer position). This is useful when explaining / discussing things in a meeting.
Such features should extend a group chat, so that you can invite externals and start a video call including these functionalities.
