	// Send a dummy request to start TDLib
	logger.debug(TG_MARKER, "Sending dummy startup request as client {}", clientId);
	TdApi.Function<?> dummyRequest = new TdApi.GetOption("version");
	this.send(dummyRequest, null, null);
	// test Client.execute
	this.execute(new TdApi.GetTextEntities("@telegram /test_command https://telegram.org telegram.me @gif @test"));

As soon as the request is sent, the Login process is initialized, preventing using a proxy upfront.
