Power Automate Help

Hello,

I'm a new Power Automate user. I hope this is the most appropriate place to ask these questions. Please let me know if not.

I've been experimenting with Power Automate in Teams, and I've run into a few questions. I would really appreciate any ideas you have.

1. When creating a flow, is it possible to automatically set the time zone to my local time? It forces me to select a default time zone. I know that it's possible to "convert time zone" later, but I'm not sure that would even work. My goal is to be able to share my flows with my organization, so if I create a "schedule a meeting" flow for them, I want the time zone to default to their local time.
2. Is it possible for automated flows to be useable on any team, chat, and channel? Like "create a task with ToDo". From all of my experimentation, it seems that an automated flow is effective on only a single designated chat or channel. Can I not create an automated flow that works everywhere?
3. Is it possible to rename flows? Occasionally, when I try to rename a flow, it will appear to be successful, but when I use the flow in chat, it will have it's old name. Thank you!

Thanks!
