Hi tax experts, I need some help

I am employed full-time in public sector in technical position, and roughly three months ago a company has contracted me to some side gigs (e.g repair services, consultation services) - around 2-3 times this year, and they have paid me around 150-200 ringgit per visit.

The company has recently asked for my tax identification number to fill CP58.

Question:
Do I need to declare income from such non-regular side gigs during tax filing next year? I don't remember the exact amount they paid me already, because I'm paid in cash. The total amount they paid me for all the services provided should be around RM 400-600, but I don't know the exact figure anymore.
