Plugin not appearing in extensions in adobe animate.

I want to download a plugin for adobe animate but it doesn't seem to pop up in the windows > extensions.

I am using Adobe Animate 2023 (latest version). Here is the plugin that doesn't seem to work: https://exchange.adobe.com/apps/cc/101161?zpluginId=101161&mediaIndex=1&mv=product&mv2=accc&product-version=5.9.0.372#access_token=eyJhbGciOiJSUzI1NiIsIng1dSI6Imltc19uYTEta2V5LWF0LTEuY2VyIiwia2lkIjoiaW1zX25hMS1rZXktYXQtMSIsIml0dCI6ImF0In0.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.gqDRbmJOOxws0vD3PHdz5z1e__YAY9Ir6HVW7V50haSzx-zl-HP9BLJk91y5OhartaNQX9NJtefgr8e6KEO7ZOzE6_CMVKxKJigqZvf2YZNmqXAsmSUIe1nyESHLVmSV_0lqr3yAl9xjLl4UryY-ckUT3br1wGHNQlT2_YId8sZjo4H2aa94I7xAuCZWZ_GxITcmbUOvbsY-erI0i5v19wpfteMilreidFfvxv9JJ3H5ajOVKe0l8i-3jttd39JQGYoK_yj26V1YQL5avySuk6py3vgNKfNKN6a0sZ8HrGCL4rg9ycBVKF8A-K56H0-h4WLW0gqE0cW746b6q_uyhg&token_type=bearer&expires_in=86399996
