Insert LaTeX and Highlight Syntax feature missing from Docs add-on

Hello admins,

I’m new to the club and must say your tool is incredible. However while the video tutorials demonstrate the insert LaTeX and Highlight Syntax I can’t find it on the Google Docs Add-on window. I need it for the sections of python code that are embedded in my documents. Are they hidden somewhere?

It is a pity if the features are retired, and in that case I wonder when will they be available again?

Thanks in advance.
