I don’t see the intercom option on my homepod

See Use HomePod as an intercom - Apple Support. It seems the feature is only active when you have two or more HomePods.

At the moment it requires 2 HomePods in different rooms. It does not show up in the HameKit app for iOS yet.

Me too I got two HomePod. Intercom not show 😬.

I try not workings. I got 3 home pod in house

Have you checked for firmware updates for your HomePods in the Home app?

My Software is updated 14.1

I don't know then. Perhaps 14.2 will fix it.
