How do you approve agents?

I have created agents however they have red sign on the request approval column. How do I approve them as there is no click to do it (like in publish/unpublish)..?

Hi,
The red icon in the column Request to approval is not important, but the green icon the agent who is requesting to become an agent in your site.
You only need to try unpublish and re-publish him, the green icon in the Request to approval will be changed to red icon.
Thanks
