Can I receive payments even without a business?

Question:
Can I receive payments even without a business? I want to start a side hustle and I did not start a business for it but would like to try it first without risking it.

Product:
Receive a payment

What are you trying to achieve:
I am trying to sell digital products without opening a business for it as it is just a side hustle for now.

What have you already tried:
I connected my personal PayPal account and it says that I must use a business account to be able to do it.

Additional information:
I have not upgraded to pro yet, so I am not sure if that would change anything but I want to check this first before losing 2-3 weeks of it on starting a business.

you can try platforms like Gumroad and buy me a coffee to sell products. And if needed, embed products on the site.
