State Machine workflow if else branch

I have a scenario that have 4 level of approvals on every approval if it is accepted it is coming to the requestor who submitted it i need to make a condition that

Approval level1=Supervisor

Approval level2=Dept Manager

Approval level3=VP

Approval Level4=HR committee

request is submitted by reguester a user

if requester reject the approval level 1 it should move to the target state 2 (Approval level2)

if requester reject the approval level 2 it should move to the target state 3(Approval level3)

if requester reject the approval level 3 it should move to the target state 4(Approval Level4)

i have a state for requestor where once the requester reject i have to move it to one target state
