Building accessible courses in Rise

Hello,

I built a course in Rise for our Travel Security Team and they reminded about a key point, that I cannot believe I did not consider when builder; accessibility for our visually impaired employees.  

I searched past discussions and nothing to recent that provides insight.  I did see a post about 4 years ago where the Articulate team mentioned this is something they are working on (should be a top priority in my opinion).  I did find an Articulate resource, "6 best practices for designing accessible eLearning" and will be looking into that for inspiration.  

Does anyone have any suggestions or examples they could share about how they made their Rise course more accessible for the visually impaired.  I would greatly appreciate any guidance, thank you.
