Create a Flow to transfer sharepoint list entries to another sharepoint list filtered

I Have one SP list called “Main” with columns “Sales Order”, “Sales Rep”, “Customer Name”, “Product”, “Amount”.

Depending on the Sales Rep Name, the respective entries of the “Main” list, should be updated with a flow to another list, so that each Sales Rep can see only their own orders (access setup for the individual lists is set).

Cannot figure out how to set the flow to filter the entries of the “Main” list and update the entries to the shortlists of each sales representative.

Any suggestion would be highly appreciated.
