Invite external testers
Invite external testers using a public link or email
9. After adding all your criteria, click Confirm. Then, copy the link and share it on social media, messaging apps, email, or any other channel.

Can you let me know how to work in Discord or "on social media, messaging apps, email, or any other channel"
Please give me some link...
Thank you.
