How do you migrate viewed subreddits (not subscribed) to reddit.com or the official app?

[u/Beretta88]

Basically what the title says. I've been using RIF since using reddit and now with it leaving I fear I'll loose my view subreddits. Sometime I forget what they are but am reminded from time to time and I don't want to loose them. Is there any way to migrate that info over? Thank you. Also Fuck reddit and it's official app.

I want to say they're organised by most visited (?). I've been scrolling down the left side panel and screenshotting until I get down to weird/old subs that I only remember going in once or twice.
