Generate a general Page Link

Hi, I would like to get your point of view with this situation I'm trying to deal with.

I would like to have the ability to generate links to the app pages without these being the current pages.

For example, if I integrate payments with Stripe Connect (via API) and I want to redirect after payment, how can I do it? Example: Payment success or error page.

Unfortunately this code doesn't work and I don't know what to do.

Thanks so much for the support..
