Choose which companies can see this permission in the dropdown. If you choose a reseller then only the companies under that selected reseller can see this group.
If you choose companies then only those companies can see this group.
Choose which companies or resellers this group will have access to. Selecting a reseller will result in the user being able to manage all companies under this reseller.
If you select individual companies then that user will be able to manage all companies that you have selected.
