import chrome from "ui/chrome" chrome.getNavLinkById("xyz").hide ...
So I found that this breaking change might be due to the introduction "new platform" API:
In the issue they show a table with equivalent API calls, where I see I could do this:
import core from '???' // <-- what should I import? core.navLinks.hide(id)
But I have no idea what to import instead of ui/chrome.
What do I have to import now?
