How to use the vscode-jsonrpc.RequestType2 function in vscode-jsonrpc

it('calls kill when request is sent', async (done) => {
    await client.sendRequest(new rpc.RequestType2('kill'), file, 'die!')

    expect(cache.kill).toHaveBeenCalledWith(file, 'die!')

    done()
  })

it('calls run when request is sent', async (done) => {
    const commands: Command[] = ['load', 'build', 'save']

    expect(await client.sendRequest(new rpc.RequestType2('run'), file, commands)).toBeTruthy()

    expect(cache.run).toHaveBeenCalledWith(file, commands)

    done()
  })
