Is it legal to sell Midjourney art on Etsy?

Could you please clarify for me, is it legally permissible to list and sell artwork created using the Midjourney AI tool on the online marketplace Etsy? I'm interested in understanding the current legal standing and potential considerations I should be aware of before proceeding with such a venture. Additionally, are there any specific guidelines or restrictions set by Etsy or other relevant authorities that I should adhere to? Thank you for your time and assistance in this matter.
