Tts calendar events using google calendar and best mini

Hi so I have just successfully setup google calendar with home assistant and now I want to use my best mini to read out the calendar events for example if I have an event at 2 pm I won’t the neat mini to tell me 30 mins, 10 mins and at the time of the event that I have the event out loud without me triggering a voice command I am aware that best mini already does this but to my knowledge I have to trigger a command for it to work and thats not automated then right so if someone can help me it will be a great help
