Explanation:

A counterclaim is defined as "an opposing claim", by Merriam-Webster Dictionary.

The complete part of the counterclaim is the following: "Critics suggest that some leaders are just as effective behind the scenes, working effectively without recognition, but the best leaders have charisma that can be conveyed through their speeches during public appearance events." This counterclaim is separated by a coma, and we can see that in the first part, the speaker mentions how effective leader are behind scenes; the counterclaim comes after " ... without recognition", and says that even though this part of working behind scenes is important, charisma shown in public events is a characteristic of the best leaders, above working hard behind scenes.
