Adding a 7-day trial to a Garmin Pay paid app: what's the official path?

I publish RuckTrack, a paid Connect IQ device app on Garmin Pay at $2.99 (store URL: https://apps.garmin.com/apps/201e9e43-f33c-4b56-b3f5-8a67184e3d1c). I'd like to offer a 7-day free trial so users can try the app before committing to purchase.

What I've checked so far:

  • Application.AppBase.isTrial() and getTrialDaysRemaining() exist in the API docs, but it's unclear whether they integrate with a Garmin Pay paid listing, or only with the older Garmin-native paid-app system. The "Trial Apps" core topic page doesn't say either way.
  • The developer portal for our listing doesn't appear to expose an "enable trial" toggle, but I may be missing it.
  • The Aug 2024 Garmin Pay launch press release mentions the 48-hour refund window but says nothing about trials.
  • KiezelPay-using apps (Crystal Reborn, Lumeo, etc.) offer trials, but they list on Connect IQ as free entries with KiezelPay handling payment outside the storefront, not as Garmin Pay paid listings.

My questions:

  1. Is there a current way to enable a trial period for a Garmin Pay paid app? If yes, what's the developer-portal step, and does it tie into isTrial() / getTrialDaysRemaining() in code?
  2. If not, is trial support on the Garmin Pay roadmap?
  3. If the only path today is to migrate off Garmin Pay to KiezelPay (or to run a paid + free-with-KiezelPay sibling pair), is that the official recommendation?

Thanks for any clarity here.
