How to Convert Button name with Tag or entity as button text using Dash/Plotly?

I have HTML Background. Just started learning Dash.
So i have font awesome library which i have imported in my .py file
ext_css = [‘https://cdnjs.cloudflare.com/ajax/libs/font-awesome/4.7.0/css/font-awesome.min.css’]

I am trying to convert following into dash:

Dropdown

html.Button(‘Dashboard’, id=‘button’, className=“dropdown-btn”),

I tried:
html.Button('Dashboard ', id=‘button’, className=“dropdown-btn”),

but it did not work and even i tried to enter some unicode using &#21e9; but it is still showing me text

DROPDOWN OR DROP DOWN &#21e9;

Could anyone suggest how to rectify the same?
