ND filter for my phone advice:)

Hey guys,
Is started a new YT channel (at the age of 40, i know:) and for now im using my Samsung Galaxy S22. I'm trying to shoot Pro Video mode, but i film mostly outdoors and where i live it is quite sunny and bright outside.
I tried once to adjust the camera to the light (again, im very new to all of this), and it didnt work, my ISO cant go too low. So, i waws thinking about the NEEWER Clip On 67mm ND2-ND32 HD Variable Phone Lens Filter Kit.

Am i dont the right choice? Im filming talking head videos outdoors, and im trying to improve my image quality as much as possible (it is a slow learning curve for me).

So, am i doing the right thing? Will you recommend it? Also, should i get the threaded or magnetic one?

Thanks for you help!
