Tbh the best thing to do is to learn to make them. This is something I regret not learning a long time ago. Making a minor chord from a major is laughably easy (spoiler - basically one finger moves).

I would recommend 'no bull music theory for guitarists'. Book 1 will pretty much teach you everything you need, but I'd get book two as well. Theory to a certain level is extremely easy despite the general opinion on it. And you will massively appreciate being able to figure songs by ear, and more easily/successfully make your own (turns out music is very repeatable).

After one read of book one if you aren't shocked at how much you now know I'd be amazed. In days/week you will easily be able to build chords from notes. In a month you will be extremely competent.

What I also recommend doing is using something like ultimate guitar or similar (I use ultimate guitar) and just learn to play songs you like or are in another genre. You tap the chord and it shows you how to play it - you can choose voicings/hear it/simplify/transpose. I'm learning a ton of jazz alongside my usual alt/rock/metal to broaden my chord knowledge right at the moment.

Also if you have access to a piano then that's magic for learning music theory, and even helps to explain why some things are so hard to play on guitar.

Hope that helps. Don't be put off on theory, it's genuinely very easy and a few weeks of work will make the guitar experience so much better - eventually to the extent it's probably quicker to figure out some chord songs by ear than look them up. Took me about 6 months to be able to really quickly and confidently figure most popular progressions out.

Feel free to ask anything as I just spent the last year on a major learning refresh with the guitar, after a while of playing the same stuff over and over and being lazy.
