Hi @Roger Roger ,
Scheduler will be available as an add-on to most Microsoft 365 licenses including Office 365 E5 license. Scheduler costs $10 per user per month with an annual commitment and $12 per user per month if paid month-to-month. Volume and partner discounts are available and the 30-day standard free trial is available for Scheduler. As to the values it brings, you can take a reference to below articles to get started:

Scheduler for Microsoft 365 FAQ
As Microsoft meeting schduler is currently not supported on Microsoft Q&A forum, I would suggest posting a new thread here: https://techcommunity.microsoft.com/t5/microsoft-365/ct-p/microsoft365 or new a service request in Micorsoft 365 admin center. Thanks for your understanding and supporting :)
