Interesting...we are working on features for the next software release that might be helpful in this context. In the meantime, the best approach might be to have your students work in pairs as "lab partners". Working in pairs would likely be beneficial for all of your students (often, two people will have complementary knowledge of the details of particular apps, or one person can be typing while the other looks things up or asks an LLM).
You might pose this same question on the Kyma Discord community (I think Jon Bellona has some experience working with BLV researchers and students, and he is active there).
