merchandise business in uae

so last year I started a small official merchandise store online, I also sold customized t shirts there and delivered all over UAE. now I don't have a physical store, my virtual store is on Instagram cause I feel like that's where most UAE people buy stuff from after Amazon, Noon and all. My business is going well Alhamdulillah and I earn enough rn that I can take care of my day to day expenses and stuff.

Now, I want to expand my business and take it to higher scale and make it more professional, I want to open a website. I'm already working on the website and 60% work is done, a friend helped me set up with Wix and create the website.

I want to know what other things I need to take care of and do, for example license and all. I asked my friend cause she also runs an online business and she said we don't need license, tbh this didn’t sit well with me so I wanted to ask other small online business owners. Please let me know if license is required and what type and any other legal stuff I'm missing
