The only GroupMe API library that isn't a million years old.

import type { APIGroup } from 'groupme-api-types'
import type { Client, Group } from '..'
import { BaseGroup, ChannelType } from '..'

interface FormerGroupInterface {
    rejoin(): Promise<Group>
}

export default class FormerGroup extends BaseGroup implements FormerGroupInterface {
    readonly type = ChannelType.FormerGroup
    // formergroup needs to share all properties with group EXCEPT sendable

    constructor(client: Client, data: APIGroup) {
        super(client, data)
    }

    rejoin(): Promise<Group> {
        throw new Error('Method not implemented.')
    }
}
