How to serialize enum in borsh-js

Trying to serialize an object in Rust and deserialize it in JS We got 000100000031 hash, after serialization this:

pub enum Service {
    Stackoverflow,
    Twitter,
    Telegram,
}
pub struct ServiceId {
    pub service: Service,
    pub id: ExternalId,
}

When trying to deserialize in JS use this:

const Service = {
    Stackoverflow: 0,
    Twitter: 1,
    Telegram: 2
}

class ServiceId {
    constructor(service, id) {
        this.service = service
        this.id = id
    }
}
const value = new ServiceId(Service.Stackoverflow, userId)

const schema = new Map([
            [ServiceId,
                { kind: 'struct', fields: [['service', 'u8'], ['id', 'string']] }]
        ]);

After deserialization, we got this, but it is incorrect because we have an object inside an object and a redundant id parameter:

ServiceId { service: { service: undefined, id: '1' }, id: undefined }

Firstly it could be because in Rust we have enum type, so how we can use enum in borsh-js. Second if not, why do we have an incorrect results?

It is hard to understand from documentation, but you need to create your class like this and all will be okay.

class ServiceId {
    constructor({ service, id }) {
        this.service = service
        this.id = id
    }
}
new ServiceId({ service: 'lol', id: 'kek' })

So you need to pass your params as object.
