How do I cancel the autorenewal?

I can’t afford to be paying for these licences right now. I got two “free” trials for my own computer and my mom’s laptop (one each, just to be clear) so I could get them working a little bit better, and I was assuming it would be easy to cancel before you AUTOMATICALLY start charging me.

I just checked the subscriptions interface in settings and I don’t see any way to cancel it.
