What documents do I need to bring for a 60-day corona extension in Koh Samui?

Hello

I have arrived on a

60 day tourist visa that allows one 30 days extension in December.

I did my 30 days extension in Phuket and I was told there that I can get a 60 day corona extension but I have to bring a contract for a house and a lot of additional documents.

I plan to do the extension in ko Suomi immigration, did any one go throw this ? What should I really bring with me for the proses ?

It’s hard for me to get a contract and staff
