Query Regarding Cash In Hand Salary Proof

There's a doubt, my appointment letter doesn't show the phrase "cash-in-hand"; instead, it mentions that the total annual employment would be 120000. Is it necessary for the appointment letter to specify a cash-in-hand payment of Rs 10,000 per month? Any suggestions? I am applying for Canadian immigration, so would there be any problems? I have been informed to submit my employment documents, including salary slips, bank statements, cash vouchers, and payslips. However, I was receiving cash in hand, and there is no salary breakdown provided with the appointment letter. Kindly suggest what I should do?

There's a doubt, my appointment letter of my previous job in a small company and current job in a hospital doesn't show the term "cash-in-hand"; instead, it mentions that the total annual employment would be 120,000. Is it necessary that the appointment letter should include the cash-in-hand payment information since I am receiving Rs 10,000 per month in cash without any PF deductions? Will there be a salary breakdown for cash-in-hand payments without PF deductions?
