What travel insurance options are recommended for staying in Thailand after extending a tourist visa?

Hi, I'm looking for travel insurance (including against COVID) for Thailand. My situation is as follows:

I arrived in Thailand on December 11 on a 60-day tourist visa. My insurance for Thailand Pass was from Tipinsure (Dhipaya), covering only COVID-related expenses. I also had a 2-month general travel insurance on my credit card.

Both those insurance policies expire today, but I have extended my visa and intend to stay in Thailand until April 3. Therefore, I would like to buy new insurance.

It should be a single policy covering general-purpose travel issues (including trekking and snorkelling / skindiving) as well as COVID (including expenses related with hospitel / hospital stays after an asymptomatic positive test).

The policies I see on the Internet are mostly for when you're not in the country yet (for Thailand pass). Do you have any advice?

Oh, I already contacted Mrs. Namak, just curious if anyone can recommend something from their own experience.
