I have successfully installed Lyx 2.3.0 and would like to install the subequations module / environment that is mentioned in the LyX wiki https://wiki.lyx.org/LyX/NewInLyX23). Unfortunately I can't figure out how to do so.
I have tried looking for the module in MikTex, but it doesn't find it, and I can't find it anywhere in 2.3.0. Perhaps it's just a matter of looking in the right place in LyX, as I can see questions (and answers) about subequations in Stack Exchange, but I haven't found the answer to my question. I'd greatly appreciate any pointers you can give me.
Sincerely and with many thanks in advance
