how to set chain_id

[vazgen]

thank you this awesome lib.

How to set my custom chain_id (as my chain id is missing in config file)?

[vazgen]

I did something like this but not sure that it is the correct way

var {ChainConfig, Apis} = require("graphenejs-ws/cjs")

ChainConfig.networks.mytest = {
core_asset: "MYTEST",
address_prefix: "MYTEST",
chain_id: "6af7b83a55a87b52d038aaf9584402edb4ec7624c1b0ec6c80b008e7987f86f2"
};
