Service Record Creation

New to PowerAutomate but have general tech/coding knowledge and currently building out an application with PowerApps.

I have two main SharePoint lists - A 'Primary Equipment List', and an 'Equipment Manager' list. The goal is to be able to submit a form where the user has selected a specific item from the 'Primary Equipment List' (dropdown > item name) within the form, then the user enters additional information (data that is not recorded on the 'Primary Equipment List') such as the action needed and progress of the task and text noting what the issue is and submits the form. Once the form is submitted, the information (item name, serial #, manufacturer, etc.) is carried over/created as a new line in the 'Equipment Manager' list. This piece, I think I have accomplished.

The next part is completing the task, and carrying the noted information back over to the selected item's service records in the 'Primary Equipment List'. Again, there are several fields that don't need to be carried back over to the main list - only the service notes field which should be inserted with the Date/Time the item was 'completed'.

My issue seems to be finding out how to transfer the data back to the main list? I'm thinking a unique ID would help but, when I try to connect a flow in power automate, it wants to reference the actual ID, which is different between the lists and just ends up changing the item name/info.

To clarify, my goal is to note the service done to specific items based on the text in the 'Equipment Manager' list. The only data I need to be carried back to the main equipment list is the service notes. What would be the ideal way to go about this, if possible?
