pub async fn add_reaction(
context: &Context,
msg_id: MsgId,
reaction: &str,
) -> Result<MsgId>Expand description
Adds given reaction to message msg_id and sends an update.
This can be used to implement advanced clients that allow reacting
with multiple emojis. For a simple messenger UI, you probably want
to use send_reaction() instead so reacting with a new emoji
removes previous emoji at the same time.
