TOPIC: SCRUM Master role in Stand up - Need Inputs

I am confused about Scrum Master Role in Daily Stand up. If there is stand up going and team members, start discussing about how to resolve issue, advisement is that SM should intervene and ask team members to take issue offline.
However, if stand up if on going and 2 team members are disrupting by side conversation - What should SM do ? Wait for the empowered, self-organizing team to resolve the issue OR wait until the standup is over and then talk to the disruptive team members OR immediately intervene to remedy the disruptive situation.

Hi Khushboo,
The answer might depend on how mature the team is - where they are in their forming, storming, norming, performing journey. The SM should help keep the daily scrum on track so immediately intervene, but if the team is mature and self organising they will likely do it themselves.
