Hi @√3RT3×. Welcome to OpenStreetMap.

Notes are one of the ways to add feedback about the map, but will not add any information on the map.

To add this feature, or fix errors on the map, you have to edit the map yourself.

Try https://wiki.openstreetmap.org/wiki/Beginners'_guide or the various self-paced guides from learnOSM.org.
