Microsoft Teams Folder TOC Setup

I need clear, quick assistance creating a clickable Table of Contents for the document-heavy folders inside our Microsoft Teams workspace. Everything already lives in Teams/SharePoint; what’s missing is a front-door index that lets colleagues jump straight to the right folder without digging.

Key points
• Platform: Microsoft Teams (with its underlying SharePoint libraries).
• Content: standard documents and files—mostly Word, Excel, PDFs.
• Organization preference: “Folders” — the TOC should mirror our existing folder hierarchy rather than sorting by file type, date, or topic.

What I’m expecting from you
1. Design and build the TOC page (could be a SharePoint page, Teams Wiki/OneNote section, or another method you recommend) so every top-level folder is listed and hyperlinked.
2. Ensure sub-folders are easy to expand or view so navigation stays intuitive.
3. Provide a brief, plain-language guide so my team can update the index themselves when new folders are added.

If you’ve set up similar navigation aids inside Microsoft Teams or SharePoint before, I’d love to see an example or hear the approach you’d take.
