Feature Request: updateDashboardHeader()

[FreyGeospatial]

It would be great to have a function to update the dashboard header, e.g, updateDashboardHeader. For my use case, I am inputting a logo in place of a title into my header. However, when activating darkmode, the logo is difficult to view. I have a logo that I usually use on dark backgrounds, so being able to switch between the two on activation/deactivation of darkmode would be useful.
