Display Document Library on Quick Launch on multiple sites - Powershell?

Heya!

I have +250 SharePoint Online subsites, everyone with their own Document Library called Customers.

I wonder if there is any way to add the sites document library to quick launch with PowerShell.

I know you can do this via General Settings but since it is so many sites and every site has the same name for their library maybe you can use Powershell to do this?

Thank you in advance!
