Custome node-red toolbar dashboard

[Henjoe]

Dear Node-red experts, especially on dashboard. I want to customize my dashboard tool-bar to be like something this: (from node-red.org web sites)

Basically, I want the user to be logged in first, then their name will be on the toolbar, like any other social media sites (facebook, twitter etc.)
Will it be possible to customize it? if yes, then how ?
Thank you very much !

With kind regards,
Henjoe
