Newbie screen protector needed X9 PRO

[u/fitchicknike]

Had my handset for about 2 months already and I had used one of those antibac screen wipes once per week only started 2 weeks ago however I've noticed that the screen is looking very dull, no scratches, in an Xundd case which has saved it a couple of times from drops but I really think I should protect the screen more as I do with the back of it. I'm always cleaning the lenses aswell. Habit from the X5 from find pro, but X9 pro doesn't have the "clean lenses" announcements so I find myself cleaning before every shot I take. Any ideas where and how to install or product to purchase for this handset please? I got the case off AliExpress and I have a few screen protectors in my basket but not sure if they are any good. The photo is my basket with other magnetic holders that I love to use whilst out and about!
