This SharePoint add-in works in conjunction with another add-in, which is only available from the provider. This requires installation on your environment outside of the Microsoft Office Store processes due the level of required permissions. A tenant administrator will need to deploy this specific add-in to the tenant manually, so that it can be installed to your environment. When apps are installed outside of the Microsoft Office Store, they may bypass any, and all, safety and security checks provided by Microsoft.
If you have not done so already, it is recommended that you establish contact with the provider before proceeding with installation. Consider trying this add-in on a separate SharePoint Tenancy before installing it on your primary SharePoint site(s).
