Is it possible to create a single meeting in a multiday conference that is open to people not registered for the conference?

I am using Zoom Events to host a multiday conference for an association (attendees will be pre registered). For one hour during the last day we will have a business meeting that is open to all association members including those not registered for the conference.

Is it possible to create one Meeting that is open to anyone with the link? And if so, how does one find the unique link to the meeting?

Ideally attendees could enter via the lobby and non-attendees would enter the meeting directly.

My back-up plan is to create a Zoom Meeting outside the event which would require attendees to leave the virtual conference space and then return to it after the business meeting.

thank you
