How Editing Contract Terms in Microsoft Word Works by the supplier in Supplier Portal

Summary:

Can the supplier in Supplier Portal edit the Contract Terms in Microsoft Words?

I would share the contract terms in word format using deliverables and I would like that the supplier can edit those files and upload the changes. When I try to sign-in using the supplier user into the doc, an error message of the insufficient privilege is shown.
