Add/ Upgrade the package in your app catalog site

Once an app catalog site is created, you may proceed to add the SigningHub for SharePoint package on it. It will provide an alternative way to your end users to install the SigningHub for SharePoint add-in from their organisation, instead of accessing the SharePoint store for it.

This is also helpful in maintaining a centralised location to add and upgrade the packages, so that all the end users of an organisation can access the same latest versions.

2. Click the app launcher icon in the upper left and select the "Admin" option, as marked with red arrows on the below screen.
