Embedding uMap: showing layers

Hi,
I’m new to programming and am trying to experiment with embedding a UMAP map on a primitive html website. I created two layers that I want to be displayed by default. However, when I paste the umap code (from “Embed and share this map”) in the html, the layers don’t show on the page by default - instead, the layers are hidden, and have to be activated from the menu. This happened even though I enabled the “keep current visible layers” option.

Here’s the code I get:

Hope it makes sense - and hope somebody can help.
Thanks in advance!
