Suggest meeting times from my Google Calendar availability

I need to offer meeting times to someone without playing email tennis.

Open Gemini in Gmail or Calendar with the side panel on so it can read my calendar.

The meeting purpose: {{purpose}}
Duration: {{duration}}
The other person's timezone and rough working hours: {{their_zone}}
My preferred working hours (AEST): {{my_hours}}
How many options to offer: {{option_count}}
Buffer either side of existing meetings: {{buffer}}
Days to consider: {{days_window}}

Look at my calendar across {{days_window}}. Find {{option_count}} slots that:
- Are inside my {{my_hours}} window AND inside the other person's rough hours
- Have at least {{buffer}} buffer on either side of existing events
- Are not in the first or last 30 minutes of my day
- Avoid back-to-back meeting walls (no slot in the middle of three other meetings)

Output the slots as:
- Day, date, time in AEST → and the same time in their timezone in brackets
- Copy-paste block for an email reply with all options listed in one block, plus one sentence offering to suggest more if none work.

AU English, conversational tone.
