Whats the max number of participants that will get displayed on a topic?

Is this on a PM in the header or this?

If it’s the 1st, I believe the logic is here:

frontend/discourse/app/components/header/topic/info.gjs

main


      
          get maxExtraItems() {
            return this.args.topicInfo.tags?.length > 0 ? 5 : 10;
          }

github.com/discourse/discourse

frontend/discourse/app/components/header/topic/info.gjs

main


      
          get participants() {
            const participants = [
              ...this.args.topicInfo.details.allowed_users,
              ...this.args.topicInfo.details.allowed_groups,
            ];
            return participants.slice(0, this.maxExtraItems);
          }
