I followed the same steps and it didn’t give either accrual entry nor individua l one, I submitted all salary slips (not from inside payroll) but couldn’t find in ledger of employees or payroll account any changes!
The salary slips don’t create accrual entries in the ledger. You need a journal entry for that, which can be created automatically by the Payroll Entry doctype.
You have to submit the salary slips from the payroll entry, kindly check the GIF attached:
Hope this helps.
