My server has no internet, what should I do?

I saw in this issue that admin_email can be skipped, but there is no input box on the page
https://github.com/baptisteArno/typebot.io/pull/1537

My .env：

ENCRYPTION_SECRET=do+Us357Bxxxxxx
DATABASE_URL=postgresql://postgres:xxx@typebot-db:5432/typebot
NODE_OPTIONS=--no-node-snapshot
NEXTAUTH_URL=http://10.8.2.70:7017
NEXT_PUBLIC_VIEWER_URL=http://10.8.2.70:7018
ADMIN_EMAIL=xx@xxx.com

You can't use it without internet connection

I want to use it within the company, only LAN

Typebot was not desgined for this...
