Where is the Unearthed Arcana Cleric 'Protection' Domain?

I have been reading that DDB enabled UA content in 2018. 

The Protection domain for cleric has been playtest in UA since 2016, and I can't seem to find it!

I have a paper campaign that is being DnD Beyondified. I'd rather not spend a lot of time putting in 'homebrew content' on DDB for it. 

Any Ideas? 

UA from before January 2018 has been abandoned by WotC and won't be included in D&D Beyond. Using the homebrew system is your only option.

I appreciate the Reply!

I best get my head around it then! 

It's 5 years too late but the Unearthed Arcana: Cleric has it, and that's on the Wizard's site, but it seems that the only way to include it in a campaign is to add it as a homebrew
