Elementor button in sidebar

I created a button using Elementor element. This button is displayed on the home page that doesn’t have a sidebar. I want the same button to be displayed on the side bar on all the other pages.
There is no option in Appearance/widgets to use Elementor to recreate the button. I wanted to copy and paste the button code to the “custom html” widget, but when viewing the page with the wordpress editor, not elemtor code or shortcode is showing that you can copy.
I looked in Chrome at the source code, I copied and pasted the html code to a “custom html” sidebar widget, it worked but I do have the css color and hover color for the button.
So the question is: How to create or copy an elementor button in a sidebar? thanks
