Take this from a guy who spent 2 years studying distribution channels [1]. There's nothing wrong about spending a week or two developing a MVP before focusing on distribution.
I think the key is to start with 1) The minimum thing you can do and call a 'product' 2) Try to promote/distribute it to see the response. So far you've done:
a) A web page explaining what your product is about
Some steps to (progressively) get to a "better" MVP may be:
b) Make a video showcasing your product (which can be a simple Figma design with static screens that show once you click on them)
c) Build a feature that's high on the ICE Scoring model [2], and distribute that
d) Build a meaningfully different feature than c) and promote it as a SEPARATE product. Let your features be like split tests you promote on the same/different distribution channels and see how they perform.
