Flow to copy content from Excel to Sharepoint

Hi all,

I was following this tutorial:

I've got the part working where it creates new items, but updating does not seem to work.

Some weird things I noticed when configuring the Update Item
In the update item settings, I link the sharepoint columns with the corresponding sharepoint columns, but once finished the icons change from excel to sharepoint icons

Also the video it shows "Title" with an asterisk, mandatory field where it checks to do the updating on. I don't have any field with an asterisk, besides ID. So I have no clue what it is using to match for update.
