While doing some investigation, I noticed an incompatibility of the Newtonsoft.Json library, which mentioned by the library owner, such support is unlikely

I decided to leave this issue because maybe in v6 System.Text.Json could be used

STJ is being used, but NAOT is a lot of work regardless and will probably not have complete support even through v6 - it's possible, but i recommend not getting your hopes up.
