Interface StoreAddSupplyChannelAction

This action has no effect if a given supply channel is already present in a Store.

Adding a supply channel produces the [StoreSupplyChannelsChanged](ctp:api:type:StoreSupplyChannelsChangedMessage) Message.

Adding a [Channel](ctp:api:type:Channel) without the `InventorySupply` [ChannelRoleEnum](ctp:api:type:ChannelRoleEnum) returns a [MissingRoleOnChannel](ctp:api:type:MissingRoleOnChannelError) error.
