Discobot doesn't respond to other users in Google Chat

I’ve added Discobot to a Google Chat room. When I send an @Discobot kudos to @roommember for… post, it works fine and Discobot responds with a congratulatory message. However, when other room members post the same message, Discobot doesn’t respond. All members are part of the Google Chat room logged in with their Google Workspace accounts.
