Hubspot Zoom app makes annoying sound every time I type in the notes section

Zoom (Mac app) does this incredibly annoying thing every time I use the Hubspot CRM Zoom app. It dings (like an error / notification sound) every time I type something new into the notes. People on the other end ask me if I've somewhere else to be and I have to reassure them no, but obviously I'd really rather the beeps didn't happen and I could silently take those notes! Can anyone put me straight on how to fix this?
