How @mentions work in Vitextra Discussions: typing @ and picking a person, keyboard navigation in the suggestion list, how a mention looks in the post, who can be mentioned, where the mention is stored (the Mentions column) and how it turns into an email notification through the Power Automate flow.
Reference for administrators and security officers on the Vitextra Discussions web part for SharePoint Online and Microsoft Teams: the four lists and the document library the web part creates on the site, how the lists are recognised by column ids so they can be renamed, which columns hold topics, replies, mentions, likes and subscriptions, where attachments and inline images are stored, what is kept in the web part properties, the identity used for every call, what is sent to Vitextra and what happens to the data when the web part or the package is removed.
