Glissando not exporting at all in MIDI

Place in question is for the Harp part on page 8 (measure 80)
If this is possible please help.
I know this was something possible in MuseScore 3, is there a way to export glissando playback information as heard on MuseScore 4 over to MIDI data in MIDI file.

When I do export the Musescore 4 file over to MIDI, everything is read fine, as printed, but there is no export of the glissando as played in MuseScore 4 to be exported into MIDI, it only exports what the music notation is marking for the start and end of the glissando.

File is attached.
