Topaz Photo AI not listed in Lightroom Classic Edit In

I have the latest version Of Topaz Photo AI 2.1.2 installed on my laptop but it does not appear as a plugin option in Lightroom Classic Photo > Edit In >
I have reinstalled and the same result. Photoshop, denoise and AI sharpen are all listed. I know I can go to File > Plug-in extras > Process with Topaz Photo AI but that is not my efficient preference. It has installed ok on my PC.
Help needed
Thanks Mark
