Pull request overview

Documentation update to add Chat button support guidance for Outlook online-meeting provider add-ins.

Changes:

• Updates the sample meeting body to include a chat link alongside the join link.
• Revises the Join button guidance to cover both Join and Chat buttons, including platform support notes and the owa-chat=1 requirement.
• Adds a new section explaining how to update the chat URL to enable the Chat button.

The first newBody sample adds a chat link without the owa-chat=1 query parameter, but later in the article you state this parameter is required for the Chat button to appear. To keep the walkthrough consistent (and prevent readers from thinking Chat button support is broken), either add owa-chat=1 to this initial sample URL or add an explicit note here pointing to the later section that updates the URL.
