How can I add an LMS.Commit/Commit Event when a custom LMS doesn't bookmark with suspend_data call

Hi all, just to weigh in on this discussion we would REALLY love a forced LMS commit option introduced in some way to Rise - either timed or triggered. We see very high volumes of learners losing progress when the single LMS commit call fails on close of window.  We have extensive instructions to the learner to click the EXIT course button (even renamed it to "SAVE & EXIT COURSE" to try and get learners to click the button before existing but efforts are futile 😩 Very keen to see if something can be done!! Even triggering LMS commit on the final slide would be legendary!
