Microsoft 365 Refund Approval Workflow

I need a streamlined workflow that takes every refund-related credit note from initial request all the way to final sign-off without leaving Microsoft 365. The request will be submitted through Microsoft Forms, captured in a SharePoint list, and then routed by Power Automate for multi-level approval. Each reviewer must receive automated notifications, and any stakeholder should be able to open Teams to see the real-time status at a glance.

Core requirements
• Multi-level approval: at least two sequential approval stages, configurable later if we add more roles.
• Automated notifications: email and/or adaptive cards in Teams on submission, approval, rejection, or comments.
• Real-time tracking: a status column in the SharePoint list and a running thread in a dedicated Teams channel so users aren’t chasing updates.

Deliverables
1. A fully functioning solution deployed in my tenant (Forms, SharePoint list, Power Automate flow, optional Teams tab/report).
2. Brief, clear documentation that lets me modify approvers or add extra steps later.
3. Short walkthrough or recording showing the flow in action from request to completion.

Please highlight your experience building comparable Power Automate approval flows inside Microsoft 365, especially where Forms, Teams, and SharePoint all interact. Links or screenshots of previous refund or finance workflows are welcome and will help me choose quickly.
