I don’t know if there are other ways to use Reddit without using its own client, but I wanted to inform you.

I heard of some web frontends that had this feature. Idk how they’re called but I think there were at least 2.
You can use Red Reader too.
Looks like Infinity is subsciption only. Just learned about Red Reader (from this thread) and it so far appears to be free, with also having anonymous browsing. Just info for anybody who might be interested in either.
It works fine for me. I got it from F-droid
Im currently using stealth for that, working pretty well so far
Stealth works as well.

Stealth is an account-free, privacy-oriented, and feature-rich Reddit client.

Can confirm this, but has some bugs like not playing some videos
I haven’t experienced that personally but Reddit’s Imgur has also cracked down on VPNs and many hosted pics and gifs will not load, depending on your selected server.
Geddit also works well as an open source, no-account needed, Reddit browser - f-droid.org/packages/geddit.buzl.uk/
