Change colors or logo in modern design problem

Hello,

I've have downloaded source traccar source, under \traccar\traccar-web\modern\src\resources\images I've changed logo.svg , then \traccar\traccar-web\modern\public 192 and 512.

In IntelliJ IDEA - Build project , in IDEA terminal ./gradlew assemble which generated tracker-server.jar in target folder.
On server side I have stopped service, removed tracker-server.jar and replaced with fresh generated one, started service but I see no changes.

Can you please help me

Have you checked the documentation?
