How to implement ToggleAction to the toolbar?

I am writing a plugin with the tool window and I want to add a ToggleAction for "GroupBy" action. Write now I wrote a class that extending the AnAction class and overriding the actionPerformed method which does the GroupBy functionality. 

But, I want to implement ToggleAction since I want to add "Selected sign (V)" once perform the action  as below,

Please find the attached code herewith,

public class GroupByActionCommits extends  com.intellij.openapi.actionSystem.AnAction {

    @Override
    public void actionPerformed(@org.jetbrains.annotations.NotNull com.intellij.openapi.actionSystem.AnActionEvent event) {
       ....
    }
}

Plugin.xml

<group id="GroupByActionCommits" text="Group By" popup="true" icon="/actions/groupBy.png">
    <separator text="Group By"/>
    <action class="action.GroupByActionCommits" id="GroupByAction.Commits"
            text="Commits" description="Group By Commits">
    </action>
    <action class="action.GroupByActionFiles" id="GroupByAction.Files"
            text="Files"  description="Group By Files" >
    </action>
    <add-to-group group-id="PluginActions" anchor="after" relative-to-action="PluginCollapseAllAction"/>
</group>
