Starting a side hustle on employee visa

Hi, I am on a single permit and have a salaried position at a company. I'd like to start a little, intermittent side hustle as a freelancer. I recently did my first small job for someone in France and was asked to provide an invoice. They said I needed a SIRET number, which obviously doesn't exist in Belgium, so they won't pay me for the work unless I can provide a Belgian equivalent.

I've since gone down the rabbit hole and it looks like I need to 'set up and register a business' here, even though I'm just planning on intermittently freelancing, and this isn't even valid on my current visa... Is there really no other way round this? Can I not just provide the French company my Belgian tax number or something? It seems ridiculous to have to go through this whole process of setting up a company for a job that was worth €70 and that I'm barely getting any work from anyway.

Any help would be appreciated, thanks.
