Problem about app install

[xfyangding]

when I install app, Browser will open a new tab, request url-1, then redirect(302) to url-2, how it work? Where can I configure this redirect url(url-2)?

url-1: https://admin.shopify.com/store/cjay-2/oauth/redirect_from_app_store

url-2: https://shopify.route.com/auth?hmac=7750a5f547f2676151dcd579d35869f50f352f7d82b69c00671b8c19143439b2&host=YWRtaW4uc2hvcGlmeS5jb20vc3RvcmUvY2pheS0y&shop=xxxxxx.myshopify.com&timestamp=1718791230&utm_campaign=admin-search&utm_source=admin
