How do I do the "Playing" status for a game?

[BackendAdam]

I have read https://github.com/aiko-chan-ai/discord.js-selfbot-v13/blob/main/Document/RichPresence.md#custom-status-and-rpc, but haven't seen how to get the game like the screenshot above, with a time. The doc only shows for "elapsed [time]", not "for [time]". Help appreciated!

	const status = new Discord.RichPresence()
		.setApplicationId('367827983903490050')
		.setName('osu!')
		.setStartTimestamp('1688992190299');
	client.user.setActivity(status);
