Why in my Dynamo on Revit 2020 not showing "Wall Opening" in the Library Search


I followed a video tutorial on the internet to make a wall opening on an MEP item that clashes with a wall.
In the tutorial there is a wall opening in the dictionary section, but the dynamo I use doesn’t exist.
Please help, thank you.

Hello and welcome…could you share the video link ?

Sorry ,I can’t share the video link because the video comes from an online course platform.
I only bought a tutorial package, so I can’t ask the dynamo trainer.

That’s a real shame to hear. I produce paid content to train in Dynamo as well, and to use an open source platform to make money and not give your time to support it or at least be available to address queries doesn’t sit well with me.

It looks like they probably used a custom node and maybe didn’t say from which package (again, not good practice by the instructor). I can’t find any node by that name in the major ones I have installed. Can you at least screenshot the library they have so we can see what packages they use in the tutorial? A bit like below…

already solved, I downloaded the same package used by the trainer.
I pay attention to the library he uses then download the same package.
Thank you for the help
