Conference one-to-one timed meetings with pre-schedule

Hello, I’m new to this, and trying to setup the following:

We want to pre-schedule one-to-one 15 minute timed meetings for each participant, jitsi seems the correct option to implement this.

We already developed the system to create the schedules based on the users pre-selection of whom they want to meet. this has been used for 4 year to now, but the event was not online.

The doubt we have is:

The correct method would be to create a new room each time the meeting changes, javascript controlled, refreshing the iframe with jitsi.

Or switching participants connections in another method ?

can anyone help with this or point us in the right path ?
