🐢 Performance warning.
It looks like the query count of the integration tests increased with this PR.
Database query count is now 84616 was 84323 (+0.34%)
Please check your code again. If you added a new test this can be expected and the base value in tests/integration/base-query-count.txt can be increased.

I wouldn't remove that code, we can still show the correct icon (same for the text).
You can use the @update:menuOpen hook on the NcAppNavigationItem in line 16, so when the menu is opened you can load the settings. I think that's the best option because then we don't show an icon only until the board is loaded and then have the correct one displayed.
