Here we see overview of all the addresses (controllers) that have some form of permission on our profile:
Keymanager overview
In the dropdown we can see list of permissions and which ones are enabled for given controller. We can toggle permissions, click save, confirm the changes and the transaction to manage permissions.
Controller Dropdown
Toggle "Change Extensions" Permission
You can manage multiple permissions for multiple controllers all at once. Meaning we can make the adjustments and only have to confirm the transaction once!
Changes overview
Confirm the transaction and wait for it to be executed!
