Can not get Shariff working with Angular 8

[kombasltd]

I am not able to get Shariff working with Angular 8. What I did

1. Install npm
2. add import to "styles.css" @import "../node_modules/shariff/dist/shariff.complete.css";
3. add script to "angular.json"

"scripts": [            
              "node_modules/shariff/dist/shariff.complete.js"
            ]

4. add div to component html <div class="shariff" data-button-style="icon" data-orientation="horizontal" data-theme="standard"></div>

Any help would be appreciated!
