This sound comes from Among Us, the social deduction game released by Innersloth in 2018. It is associated with the in-game meeting and voting interface, where players discuss who to eject and then confirm a vote. As Among Us exploded in popularity in 2020 through streams, YouTube videos, and short-form memes, small interface sounds like this became recognizable on their own. It is still used because a one-second game cue can instantly communicate commitment, suspicion, or a point of no return.
