Can I mention on Linkedin a project outcome I had on Upwork?

Hi everyone, quick question regarding Upwork policies.

If a freelancer completes a project through Upwork and the client explicitly agrees, is it allowed (from Upwork's point of view) to mention the company and the project outcome in a LinkedIn post (for example, saying that we assisted the company with a trademark registration)?

No screenshots, no private messages, and no financial details would be shared — just a general professional mention.

Does this comply with Upwork’s terms of service? Is it allowed to ask my client for permission?
