The tile's chip while an agent can see the participant: "Agent can see" / "Agents can see".
The self-view's badge while the user's frames reach an agent: "Agent can see this" / "Agents can see this".
The start of the notice when the choice couldn't be saved: "Couldn't change what the agent sees" / "... agents see".
The control's label while they can: "Hide from the agent" / "Hide from agents".
The control's label while agents can't see the user: "Let the agent see me" / "Let agents see me".
The control's name while agents can't see the user; it says the choice covers agents that join later.
The control's name while they can; it says the choice covers agents that join later.
The words the media kit uses for whether agents see the user: the tile's chip, the self-view's badge, the agent-vision control, and the notice when the choice can't be saved. They are plural only in a room with more than one agent; a call with one agent says "the agent". The choice is room-wide: every agent in the room honors it, including agents that join later, so the control's name says so in both wordings.
