Here's how to update your deck URL:

1. Go to your Data Room / Folder where your deck is stored
2. Find the deck file and click the paperclip symbol to the right of its name
3. Select "Copy file URL to share"
4. Now go to Settings > Variables in the left-hand panel
5. Find the deck_url variable, paste the copied link into the Value field, and click Save

Once saved, the {{fund_details.deck_url}} variable will automatically pull that link whenever it appears in your email templates.
