Why don't I have the Animation extension?

Hi, I have Avogadro2 (version 1.99.0) and I need to use the ‘‘Animation’’ extension to visualize molecular dynamic trajectories (.traj). When I click on the ‘‘Extensions’’ tab, the ‘‘Animation’’ option is not present. I tried the option ‘‘Download Plugins’’ to see if I could download the extension but ‘‘Animation’’ was not on the list of available plugins. How can I get the extension ?

Thank you for your help

In Avogadro2, it’s not an extension. See the little movie icon, second from the right. That’s what you want.
