Recording Announcement - so jarring!

I've begun a series of guided meditations via Zoom and am recording them.  The announcement that the recording is on and then off is so so so loud and disturbing. Is there a way to adjust that volume?  If not, I'd like to strongly request a change - a softer voice perhaps preceded by a gentle tone.  The tone would help prepare the participants that an announcement is coming.  I end my recordings while my participants are still on so we can have a bit of conversation.  The current announcer voice that the recording has ended is just awful.  Please!! Can something be done?!?
