How to use the @glimmer/runtime.clientBuilder function in @glimmer/runtime

appendTo(selector: string) {
    let element = assertElement(document.querySelector(selector) as SimpleElement);
    let self = new UpdatableRootReference(this);
    let cursor = { element, nextSibling: null };

    let handle = unwrapTemplate(this.template)
      .asLayout()
      .compile(this.syntax);

    let templateIterator = renderJitMain(
      this.runtime,
      this.syntax,
      self,
      clientBuilder(this.runtime.env, cursor),
      unwrapHandle(handle)
    );
    let result;
    do {
      result = templateIterator.next();
    } while (!result.done);

    this.element = firstElementChild(element)!;
  }
}

getElementBuilder(env: Environment, cursor: Cursor): ElementBuilder {
    return clientBuilder(env, cursor);
  }

getElementBuilder(env: Environment, cursor: Cursor): ElementBuilder {
    return clientBuilder(env, cursor);
  }

getElementBuilder(env: Environment, cursor: Cursor): MutElementBuilder {
    return clientBuilder(env, cursor);
  }

getBuilder(env: Environment): ElementBuilder {
    return clientBuilder(env, this.cursor);
  }
}
