An 'invite to which' or an 'invitation to which' or 'whose invite'?

All prompts and learning resources will be released on our Discord server, and an invite to it shall be e-mailed to the participants on registration.

I am adding the previous sentence to an official document and am quite confused as to how this sentence shall be structured as something about it does not sound good right now.

I google’d the use of ‘whose’ for inanimatable objects and got weird answers so could not decide if I could say …on Discord, whose invite shall be sent…
and, I also could not decide if it would make sense to say an invite to which shall be sent or an invitation to which shall be sent.

There are three aspects of this question and I still am quite confused, what is the best way to convey the message?
