Any Web Part is provided in 3 different packages, all following Microsoft guidelines:
For Classic Experience:
- Add-in, for tenants with a configured App Store/Catalog.
- WSP, no-code sandbox solution, (recommended) whenever sandbox is available.
For Modern Experience:
- SPFx, SharePoint Modern Pages.
After unzipping your Web Part package, you will find three folders: - App; - Wsp; - Spfx
You will be using one of these folders to install the Web Part.
