Rmarkdown slide smoothing, plus grays for non-current sections

Question

I want to insert a smoothing slide at the beginning, but not at the very beginning.

In addition, I want the content slide to repeat each time a new section appears, but from now on everything is grayed out except for the current section, for example, see image.

( this other answer will not work, because toc: true just puts one table of contents at the very beginning)

Some KIND answers exist in Latex (see here ), but I don’t know how to implement them as part of markdowns. More generally, I find it difficult to integrate liner-based latex into rmarkdown, so if someone can show me how to do this, esp with this example, this is useful.
