Running Art Commissions and Etsy with LCWRA

So for a while, I believed I couldn't do any kind of work at all on this, but I've been reading around and seen work is allowed so long as it isn't contradicting to what was told to them originally.

I am mostly non verbal outside of my family and friend groups, and likely to have panic attacks in stressful situations (any kind of "normal" work essentially), however, if I could use my skills (art), so I can do commissions or run a small Etsy store, without it affecting my LCWRA, it would honestly give me a sense of accomplishment in my life, like others, I really want to work, do something with my life, but I struggle. But being able to do art commissions or run a small Etsy, I don't feel like it will stressful, I know if I get any clients that are likely to stress me out, I can essentially stop working with them, it's not like shop work where I would HAVE to work with the stressful customer.

I know it's not advised to talk with DWP or whoever runs it in my country (NI) before I start earning as it will only confuse them, it will also not be stable money, there may be some months I make quite a bit, and there may be some months I make nothing at all, an artist is not a stable job, I would however love if it turned into one for me. It would give me much more freedom, but I know that's not likely to happen.

I just want to clarify here that I don't need to be permitted like it was on ESA? That they literally do encourage you on UC to pick up a small job? Like on my journal, I noticed they had sent me a thing about small businesses, actually exactly the kind I'm sort of referring to it, it was for a craft shop in the town that lets artists have a space in the shop to sell their crafts/artwork, I would have attended but it conflicted with something else I was going to.

Can anyone give me a run down of exactly what is allowed and not allowed? What do I have to watch out for when attempting this kind of thing? Can anyone tell me their own experiences if they also do this sort of thing on the side?

I am set up to go for something for help, kind of related to this in a way, but was more when I was panicking when the government was talking about doing away with benefits for people like me that only have a mental disability… I am only just now getting that appointment in April!
