Gutenberg support for catch base Pro?

I've finally disabled the classic editor to start working with Gutenberg blocks on my posts. I notice that I don't have wide or full layout block options and I'm wondering if this theme simply isn't/ or won't be supporting these functions. If so, might you be able to give a quick list of other functions that will not be available with Gutenberg and this theme? I've looked in the documentation and there is no mention of these features (and/or limitations). I really like this theme but would just like to know what I won't be able to use with Gutenberg going forward. Thank you, Lisa G.
