Sometimes, especially when in a call with audio only, I’d like to agree with what someone is saying. We usually do it with thumbs up on camera. It would be good to have a thumbs up reaction just to support what the person is saying without a camera.

It could work like reactions on a live in Instagram: it appears for a while and fades.

It could also be personalized with different emojis or something like this.
