How to link two list in SharePoint Online

Dear Members,

I would like to link list A and list B in SharePoint online. I like to get the column value of "Approval Status" in list B to list A by matching the "File" column. 

List A- Columns: File, Modified Date, Comments, Approval Status

List B- Columns: File, Approver Status

How can we pull the Approval status value in list A from list B using any out of box method?

Any suggestion or an alternative solution is appreciated?

Thank you very much for your time and support.

Regards,

AK
