How to buy Hello Labs?

Hello there, I'm interested in investing in Hello Labs, but I'm a bit unsure about the process. Can you guide me through the steps of buying Hello Labs? Do I need to sign up on a specific exchange? Are there any specific requirements or documentation I need to submit? Also, are there any fees associated with the purchase? I'd appreciate it if you could provide me with a clear and concise explanation of the entire process. Thank you!
