Trackers for bicycles

[zmudshark]

If anyone puts an AirTag, or similar, on their bike, how do you affix it?

I was looking at these:

Or these for under the seat:

Any real world experience is helpful. I'm having work done at my AZ condo, and though the bikes will be locked with cables, I'd like something 'just in case'. I trust the contractor, but the garage will be open, and I won't be there all the time.

Thanks!
