What would be a nicer way to paraphrase this message shown to the user "User unauthorized. Please make sure that you are a member of our Discord server".?
Here are a few suggestions for a nicer way to paraphrase the message:

1. "It looks like you're not a part of our Discord community yet! Join our server to access this feature."
2. "We couldn't verify your Discord membership. Please join our server to continue."
3. "You're not authorized to access this feature. Make sure you're a member of our Discord server and try again."
4. "Whoops! It seems you're not connected to our Discord server. Join us to unlock this feature."
5. "To access this feature, please ensure you're a member of our Discord community. If you haven't already, join our server and try again."
6. "We're sorry, but it appears you're not a member of our Discord server. Join us to get started!"
7. "It looks like we're missing you on our Discord server! Join us to access this feature and more."
8. "Please note that this feature is only available to members of our Discord community. Join us to get access."

These rephrased messages aim to be more friendly, inviting, and helpful, while still conveying the same information to the user. They encourage the user to join the Discord server, rather than simply stating that they're unauthorized.
 Here are a few possible ways to paraphire the message to make it sound nicer:

* "Access denied. Kindly confirm your membership on our Discord server for authorization."
* "Sorry, it seems that you are not currently authorized. Please ensure that you are a member of our Discord community to proceed."
* "Unfortunately, you do not have the necessary permissions at this time. To gain access, please join our Discord server and try again."
* "It looks like you need to be a member of our Discord server to continue. Please sign up and return to try again."
* "Authorization failed. To unlock access, please become a member of our Discord community and try again."

These alternative phrasings aim to be more polite and encouraging, while still conveying the same information as the original message.
