The short answer
Split it into two permissions. Reading availability is safe and immediately useful: 12 entries here are tagged with it. Writing an event holds somebody else's time, and that is the one to keep behind an approval until you trust the chain feeding it.
The two jobs, deliberately separate

The three rules that keep this boring
- Never let the agent invent availability. It must read the calendar, not reason about it.
A confidently wrong time is worse than no answer.
- Routing is a business rule, not a judgement call.
9 entries are tagged route an inbound lead. Owner,
territory and round robin logic belong in the routing tool where they can be audited, not in a
prompt where they cannot.
- Confirm in writing, to a human. The agent's last step is a message a person can read and
cancel, not a silent calendar write.
Where scheduling coverage actually sits
Scheduling & Routing has
6 official servers and
2 community across
14 entries, with
7 entries whose access gate could not be
established from public sources. It is a middling category by coverage, which is worth knowing
before you design a flow that assumes the booking step is the easy one.
