Is this a root?!? 🙏

Hi everyone,

I’ve been propagating an anthurium for about three weeks now in sphagnum moss. Ive been unsure about the humidity level but the node seems alive. I’ve noticed this white speck appear – any chance it could be the beginnings of a root?! I’m really hoping so. But would be grateful if someone could confirm or tell me I’m deluded – either way would love an expert opinion. Thanks!
