Escaping JSON in PowerShell When using the --clientSideComponentProperties option it's possible to enter a JSON string. In PowerShell 5 to 7.2 specific escaping rules apply due to an issue. Remember that you can also use file tokens instead.

Additional Info

Some things to consider while building.

• we need to insert an item in the TenantWideExtensions list for this command. We can reuse the existing listitem add command for that.
• we need to check if an app package is available and if skipFeatureDeployment is enabled / the app is deployed to all sites, otherwise the addition to the TenantWideExtensions list will fail.
• we need to check if the app package contains an extension that can be deployed tenant wide.
• We would need a note in the docs saying you need to be a SharePoint admin to deploy tenant wide.
