UAE taxation question

Hi all! I am a resident of UAE for 2 years and just recently my bank requested a Tax Identification Number (TIN) despite the fact that I am not an entrepreneur, and my annual income falls below the tax threshold of 375,000 AED. As per law I am still a tax resident of UAE.

I have a question regarding the so-called CRS form.
Should I request the TIN form the authorities or I just send the form explaining why I have not got one?

EDIT: missing link to the CRS info added
