Dash bootstrap component: how to change the Navbar toggler default icon?

Dash Python

Yes, I already figured out that the default icone is defined with

.navbar-light .navbar-toggler-icon {
  background-image: url("data:image/svg+xml,%3csvg viewBox='0 0 30 30' xmlns='http://www.w3.org/2000/svg'%3e%3cpath stroke='rgba(0, 0, 0, 0.5)' stroke-width='2' stroke-linecap='round' stroke-miterlimit='10' d='M4 7h22M4 15h22M4 23h22'/%3e%3c/svg%3e");
}

Problem is, I dont know what kind of URL is that. What is “data:image”?

I’m opting for the second solution, that is creat a toggle with a Button +navbar-toggler class +another icon

Will update this post once I have something decent

Actually, if the below post had a correct title, I would have found it earlier:
