Workflow stops after submission

Hey Everyone, I want to create a workflow approval for Payroll entry that will involve the document moving through 3 different approvals after the document is submitted, So basically I want the following transition to happen:

All the states except Pending and Cancelled are submitted states(1)
I have noticed that as soon as the HR manager signs the document the next actor does not get a notification, but they will be able to approve or reject the document if they manually navigate to its location, the next actor getting a notification is important for the completion of the end to end process, Any assistance with this will be appreciated.
