How to invoke a SharePoint workflow by updating ONLY the value in a list item (approved, not approved)?

Question

I am new to SharePoint but quickly find out.

I want to call a workflow only when the value is updated in the list item, but not every time the item changes. For example, I have a column for approval / not approval, and I want it to be a trigger, and not other values ​​in the element. Therefore, if anything else changes, the workflow will not start unless the “approval” value is specified.

All help is appreciated!

Thanks,
