Want to start affiliate marketing, what is the best and simplest way to start? And get about $300 to $500 a month?

I want to start affiliate marketing, don't want to make a business out of it, I'm looking for kind of a side hustle.

I already know fb and google ads, however I would like something in the lines o a passive/organic income, without active and paid marketing.

Is the simplest way affiliating to a course on Click Bank and try to get viral videos on IG, TikTok, YT etc, and setting the link in bio?

And, yes, I know how hard it is to make affiliate marketing actually make money.

A little observation, I'm from a third world country, so you don't need imagine that big of income necessary, something like $300-500 is huge and enough.
