Use with LearnDash LMS plugin?

I’m building an eLearning site using the LearnDash plugin. Although the Hypothes.is plugin works well with any WordPress pages and posts, it does not work with LearnDash pages (which are called ‘courses,’ ‘lessons,’ ‘topics,’ ‘quizzes,’ etc.).

I have tried to explicitly add the post IDs of the LearnDash pages in the below fields in Hypothes.is settings, but with the same results (the toolbar does not appear).

Allow on specific posts (list of comma-separated posts IDs, no spaces)
Allow on specific pages (list of comma-separated pages IDs, no spaces)

Could this be because LearnDash uses a different post_type? If so, would it be possible to include a setting to the effect of “Allow on specific post_types (list of comma-separated post_type identifiers, no spaces)”)?

Thanks so much for your work on this plugin.
