Question about Installing Plugins

I have a MacBook Pro with M1 Max. Currently Monterey is my operating system. I am a Lightroom user and sometimes Photoshop. I recently purchased Denoise Ai, Gigapixel Ai, Sharpen Ai and Topaz Photo Ai. The Plugin for Topaz Photo Ai shows up as a plugin in Lightroom, but I do not see a plugin for Denoise Ai, Gigapixel Ai or Sharpen Ai. Are these strictly stand alone programs without the option for plugins? Did I do something wrong? Please help! Thank you. Penny
