Maximal Ideals of $R_f$ can be identied with those maximal ideals of R which don’t contain f

Question

Assume $R$ to be finitely generated over an algebraically closed field.

I proved that prime ideals of $R_f$ can be identified with those prime ideals of $R$ not containing f. But I don’t know how to proceed for maximal ideal.

Any hlo isn’t appreciated!!
