Should I send a friend request on insta?

So there is this girl i found kind of cute in my college (batch), its just starting of the semester , she doesn't have that much of friends, I haven't talked to her till now , also not approached her,

Should i approach her to ask for her insta ( which infact i already have), or just send a request online without approaching. ?
