No offical Adam merch?

Hey everyone,
quick question because I’m honestly a bit confused.

Is there a reason why there’s basically no official Adam merch, or am I just blind?

So far I’ve only seen some trading cards and the Youtooz release, but nothing beyond that. No shirts, posters, or figures like other characters seem to have.

Is this a licensing thing, a popularity decision, or just how the merch rollout worked?
I’d really appreciate some insight if anyone knows more.
