Question About Sharing My Calendar With Non-Subscribers

Hello,

I recently purchased a Pro subscription to use Kalnext for annual planning at my church. I have my Pro account set up and my calendar is created and synced.

Can I invite three other individuals to view or collaborate on my calendar without each of them creating their own Kalnext account?

If they do need accounts, do they each need to have their own paid subscription, or can they participate under my Pro plan?

Thank you for your help!

Best,
Joel
