Likely impacts:
On first open, you could label the first two taps as small acts of compliance, so each tiny yes builds the foot-in-the-door towards a bigger ask.

Try framing a trial with a step already completed, e.g., setting goals, so users feel they've already started and are more likely to carry on.

When users set their own goals, consider labelling the button with a first-person line like "I'm committed", so the click itself becomes a small first yes.

It may help to ask when users would like to hear from you before requesting notification permission, so that small choice leads naturally into agreeing to alerts.

One option is to offer a reminder when someone declines a bigger request, like paying, turning a 'no' into a small yes that may make agreeing later more likely.

Starting sign-up with a few tiny, relevant yeses could increase conversion, as users who've acted on small steps may be more likely to agree to the bigger ask.
Small early commitments, e.g., setting a goal, might boost users' motivation to put in effort, as the foot-in-the-door makes carrying on feel consistent with their choice.
