Zoom Meetings and WIX

Hi, I'm using WIX to launch the MVP and test my service.

My staff is made by 7 users who will use ZOOM Meeting (throught WIX) with their clients who will book an appointment through my website (WIX). 

They need more than 40minutes call. Do they have to upgrade their base Zoom subscription or can I upgrade the default ZOOM Meeting account on WIX and consequently the staff can benefit of my upgrade?

Any solution?

Thank you
