Automatic update of sharepoint list from modified excel generated by forms

[SuzPang]

Hello community!

I am trying to create an automation for this process.

1. User A fills in a Form ("Asset Profile Form") created via MS Forms.
2. Response is automatically added to the Forms-generated excel spreadsheet ("Asset Profile ss") that I've saved on sharepoint. The info entered at this stage is marked in the Asset Profile ss as Part 1 
3. Part 1 info is displayed on Sharepoint as an item on a List ("Data Inventory").
4. The List is viewed by User B to assess Part 1 info's classification 
5. User B edits the Asset Profile ss by selecting from drop down in Part 2  
6. Data Inventory is automatically updated with the Part 2 info

I have made a basic Forms -> Sharepoint flow to cover 1-3. 

How do I incorporate an Excel -> Sharepoint flow for 5 & 6, and generally for when any part of the Asset Profile ss is updated?

Thanks for reading! Regards, suz
