Chat: Right Click Char to Whisper Does not Work

[nitoygo]

Describe the bug
Right clicking another character to put name in whisper target does not work

Steps to reproduce the behavior:

1. Login Player1 Player2
2. In Player1's screen, press enter to show the chat input box
3. Right click on Player2
4. Notice that the name of Player2 is not copied to the target name for whisper

From the code, it seems LBUTTON is used. Can anybody confirm if it should be left click or right click?

    auto const releaseMouse = SEASON3B::IsRelease(VK_LBUTTON);

    if (SelectedCharacter >= 0 && (IsVisible() && releaseMouse))
    {
        auto const character = &CharactersClient[SelectedCharacter];

        if (character->Object.Kind == KIND_PLAYER
            && !gMapManager.InChaosCastle()
            && !(::IsStrifeMap(gMapManager.WorldActive)
                && Hero->m_byGensInfluence != character->m_byGensInfluence))
        {
            SetWhsprID(character->ID);
        }
    }
