How Can I Extract Data From A Subreddit Over Multiple Years (e.g. 2018–2024)?

Hi everyone,
I’m trying to extract data from a specific subreddit over a period of several years (for example, from 2018 to 2024).
I came across Pushshift, but from what I understand it’s no longer fully functional or available to the public like it used to be. Is that correct?

Are there any alternative methods, tools, or APIs that allow this kind of historical data extraction from Reddit?
If Pushshift is still usable somehow, how can I access it? I’ve checked but I couldn’t find a working method or way to make requests.

Thanks in advance for any help!
