I feel as though I may be missing your question, but I want to say it's as basic as understanding there can be a broad range of challenges that people may have that are not visible and that you can't necessarily build for or expect standards to automatically be adapted to. Rather, how we present ourselves can encourage people to tell us what their challenge is and how we can support them as a service provider.
I personally approach this by being open-minded and by understanding that we probably have less representation in our workforce than we are even aware of in terms of the people who will self-report as having challenges. The same thing is true for the society we serve.
What we need first and foremost are people with lived experience. We need as well to represent ourselves in such a way that customers will come forward so we can truly understand the adaptations and service approaches they want.
