Can you use warcaster to cast Eldritch Bolt as a Attack of Opportunity even if you’re level 5?

@JeremyECrawford can you use warcaster to cast Eldritch Bolt as a AoO even if you're level 5 or higher?

The 3rd benefit of War Caster requires you to target only the moving creature. Eldritch blast works as long as all the beams target it. #DnD https://t.co/WWjgiHQgtD
