Samourai Server + Sparrow implementation (help)

I use sparrow as my main wallet to do coinjoins. I already have my sparrow wallet connected to my umbrel node via electrs. I was wondering if I should also download Samourai Server app to help with the anaonymity of my coinjoins? How exactly would I do this since I am already connected to electrs with sparrow? Any help or clarification would be great. Thanks :smiley:
