Preparing for your meeting

Hi there, I have an upcoming workshop which has been scheduled. I am the admin. I wanted to ask if I can join the meeting ahead of the scheduled time just to check settings in the meeting environment? One of the things I wanted to check were the breakout room settings (I have pre-assigned participants) e.g. enabling screen share in breakout rooms. However, if I do this will it notify everyone that the meeting has started? I'm concerned about messing up the meeting / causing confusion if I do this.
