Which is a free online database you can use with unity and node.js?

It should be able to only store Text and it should have a simple design to manage everything like firebase because I am not familiar with Databases.
The payments should be the same as supabse’s – 1GB storage and unlimited write/read requests.

I tried using Supabase, MogoDB and Firebase but non of them worked for me, since it should work for untiy Desktop builds…
