Cannot find UX Macrocomponent in UI Builder

[saint]

Hey Experts, I have this page which redirects all my business stakeholders to a certain page. I want to configure this page but unable to find it in the UI builder. Please guide. 

Thank you!

@saint The screenshot you shared doesn’t seems to be part of SOW, what exactly is that

based on my research this page was crerated using UI builder, I'm not sure myself, where does the UX Macrocomponets are configured, but I've checked all the lists in the UI builder, Experiences, Pages, Components and I can't find this there.
