Do I need to do a 90-day report while on a Covid exemption in Thailand?

I entered to the country on November with Tourist Visa. After 60 days, I extended the visa for one month. (That's my all 90 days tourist visa days).

I am on Covid exemption now.

My question is;

- for the 90 days report, do I need to do it, as the days the immigration office granted the Covid visa was on the 89th day (from my entry) and when I tried to report, the day after I got Covid vis, via online, it said REJECTED.

1. Do I need to be concerned? Or just assume I don't need to report separately that they already registered my over 90 days stay?

And when they granted, some notifications added:

Holder must leave the Kingdom within the date specified herei, offenders will be prosecuted.

2. Does it mean this is my last chance to stay in the country, and when this validation ends, I MUST leave the country (no option for applying any other visa)?

Thanks in advance.
