Use the Button add-on to insert a call-to-action link or provide a way to download the file. Basically, this add-on allows you to apply different Bootstrap 4 styles. The widget supports all styles of Bootstrap buttons, as well as allows fine-tuning of classes, styles and attributes of the tag.
The Button add-on closely integrates with File Manager add-on, which allows invoking the uploading dialog directly from the button editor. This way you can upload a zip, a document or any other file and instantly get a link to it.
You can insert new buttons or transform existing links to buttons (and back).
