Do Dexcom ONE+ alarms sound in Silent mode or a Focus?

What Dexcom ONE+’s own apps (Dexcom ONE+ app, Dexcom Follow) do, from the maker’s documents.

No

ONE+ alerts do not override the phone's settings. If the phone is on silent, vibrate or Do Not Disturb, you do not hear the alerts. Follow app notifications also follow the follower's phone settings. (Dexcom user guide, p. 42; Dexcom user guide, p. 10; Dexcom user guide, p. 48)

Dexcom ONE+ is not sold in the US. All facts here come from Dexcom's UK and Ireland pages, the UK App Store listing and the outside-US English user guide (mmol/L). Dexcom says Share and Follow may not be available in all regions.

With Glide

Partly

Glide's banners are Time Sensitive: they can appear during a Focus that permits them, but do not bypass Silent. Its overnight call comes from a contact with Emergency Bypass on, which rings through Silent and Focus (Premium). (/lost-signal-call)
