Looks like it uses RSA so what I said above I think still applies.
EDIT: It is called JWE or JSON Web Encryption for help with what keywords you should search. There are also other symmetric algos you can use with RSA like chacha20, but I think it is best to start with AES just because it has been used for years and is very well documented.
TIL that RSA allows maximum 245 character payload. But I guess that doesn't apply to JWE. Thanks for the suggestion, I'm researching ๐๐ซก
