Baron and Kenny 's mediation method

Hi! Everyone ! I heard that we can examine one mediator mediation effect through Baron and Kenny approach; and the hypothesis should be set like this on below:

H1: x predicts m
H2: m predicts y
H3x predict y

however, I am wondering if it possible for me to test a mediation effects with two mediator with baron and kenny method ?if so, how should I write the research hypothesis regarding the mediation effect between X and Y for this model with baron and Kenny method?
Should I set my hypothesis like that with baron and Kenny method? or there are more hypothesis I should set in order to test mediation effect?

H1: x predicts m1

H2: m1 predicts m2

H3: m2 predicts y

H4: x predicts y
