We give remote trainings with openLCA quite frequently now, if your screen is too large so that a full page is not really visible, then you can change openLCA to not cover the full screen but a separate window, and share this window then only, that should allow you to scale to the size that fits. Maybe you can comment back if this works for you, thank you.
So instead of transferring this window in zoom (full screen)
transfer this window (application window)
are you able to follow ;)
