Hi @rmerritt ,
Yes, Selenium IDE options were available in Power Automate Desktop. However, it’s important to note that Selenium IDE is deprecated and it stopped working after February 28th, 2023.
The Link you have provided its self has mentioned the same also.

So Now we dont have that option.
(Note:- if you got your solution you can mark as solution and gives kudos)
Thanks & Regards
