[FEATURE] Authorization header support

[lucianopf]

Is your feature request related to a problem? Please describe.
It would be awesome to have this project working smoothly with private endpoints that requires an Authorization header.

Describe the solution you'd like
Add either an option to add this directly to the component as to its demo website 😬

Describe alternatives you've considered
Maybe it could have a checkbox like Requires Authentication and than when the user press it it could enable another input that would accept a valid value for the Authorization header 🤔

Very good point! It sounds like adding this option on the demo site would be really simple.
