What process should be undertaken to get feedback from white-label clients?

I'm currently working with a company that distrbutes their white-label product and I was wondering what is the best process in order to get feedback from clients in regards to how their customers are finding the ux? My suggestion is to use analytical tools such as Hotjar and FullStory.

I want to appeal to their self-interest by reiterating that by using these tools, we get rich data that enables us to make improvements to the UX which will eventually benefits them because they use product

Are there alternatives ways to collect UX data from clients and how often should it done?

Your thoughts are appreciated Thanks
