Remediations to non accessible interactions

Hi, I am writing modules in Rise following accessibility requirements as much as possible, but some times I need to use interactions, even just images with content, that I know are not fully accessible yet. I am therefore thinking of adding the content of the interaction in a separate fully accessible document, to download if needed. This will be announced in the intro to the modules so that learners are aware. I know this is far from being the best solution, but I cannot think of anything else. Any  comment/ suggestion would be much appreciated. Thanks!
