Should SaaS products have a generic NPS link pinned to the dashboard?

Generally, NPS surveys are sent over on email or presented as a pop-up. However, is there any research on finding on having a persistent place in the dashboard to trigger the generic NPS form?

Patagonia's old website is one I could find which has a permalink to the NPS followed by either triggering specific feedback and/or generic feedback the user can use to point and select which element they're referring to.

Wanted to know the best practices around the same and/or more examples or if this approach should even be considered.
