Can't share links into discord

I've made a TON of homebrew, I wanna share this with my players without them sifting through their inventories, spell lists, species list etc. I've tried copy pasting the link into a channel on my discord server and they get a 404 error when clicking on it, when looking into this topic I found old links that used to work that have the same format give the same error. Is there a way to share a link to a piece of homebrew that isn't published without it 404 erroring? Note the person I used for testing the links is in one my campaigns that also has content sharing enabled, both of us have master subscriptions and there is no corruption in the link.

Not sure why it would be doing that. Sharing a campaign with them is the way to share unpublished homebrew via links. Is the homebrew in your collection (as in, you haven't clicked the button to remove it from your collection)?

Its all homebrew I have made and is actively in my collection.
