Hi @justinegeffen, writing here what I shared on Slack, so everything is in the PR just in case we want to double-check someday.

Just show up, I didn't work in the UI.
What I found is that since the desktop header is custom, we need to explicitly import and add the component there. On mobile it shows up by default because the header isn’t custom. (Not a big fan of Docusaurus 🫠). The fix was essentially importing it into the correct file.
In mobile, it was not properly displayed due to a style overwrite.

Change was implemented.
