I have a code

class Base {
    static text: string;

    static set(text: string) {
        const self = class extends this {};
        self.text = text;
        return self
    }
}


class ChildBase extends Base {
    static print(moreText: string) {
        return moreText + this.text;
    }
}


ChildBase.set('good').print('prefix')
                      // Error TS2339: Property 'print' does not exist on type 'typeof self'. 

How to call print after the call set static method. I need clone class before calling another static method in ChildBase
