viewer("https://forum.posit.co/c/quarto-r-markdown/10-2.html", 
       height = "maximize")

Error in viewer():
! could not find function "viewer"

viewer() is not a rmarkdown function

I don't know which function you are looking for. This issue means that the function doesn't exists.

You need to use the right function.

Why are you opening in the rmarkdown github repo exactly ?
