is this a reflexive word? “You choose a lesson that is not too difficult for you” the is not directed towards myself the object?

“sia” means “is”. It’s the subjunctive equivalent of the indicative form “è”. Would you please show the context? I’m not able to access the lesson through the provided link right now

Oh, now I can. “Scegli una lezione che non sia troppo difficile per te” = “Choose a lesson that is (sia) not too difficult for you”

So, “si” is reflexive = him/her/itself, themselves
but “sia” is a verb = is

Ok mood tense, so does this ‘sia’ fall under “impersonal statements”? because I’m unsure otherwise how it falls under the subjunctive tense described.
