To ensure your staff is able to download the Shogun Page Builder app to your Shopify store, the following staff permissions will need to be selected on their store profile:
Blog posts and pages
Manage and install apps and channels
These are the minimum requirements for their staff account to download Shogun, but more can be selected and it will not effect the app install.
Please note: If you'd like your staff member to have the ability to upgrade and select a paid plan on Page Builder, the "Approve app charges" permission will also need to be enabled.
