Hi USA80,
From your screenshot, you have selected Microsoft Dataverse--When a row is added, modified or deleted,
Use the filtering columns box to define a set of comma-separated, unique names for the table, so you need fill logic name of the fields.
You can refer following link to know more about it:
Trigger flows when a row is added, modified, or deleted - Power Automate | Microsoft Docs
Then you can refer following steps.
1.Trigger:
I selected composite address1 as trigger filter, you can also select other fields as your needs.

2.List Rows.

3.Update a row.
For example, i just use one address1(city) field to test, you need fill fields of address as your needs.

Overview:
