I can't get 'start_url' to work for me

[marcbejar]

I hava a NUXT App that has 4 main routes:

/ -> The index page that will act as the sales page.
/pro -> The dashboard where registered users can set a profile with a username
/auth -> Where users signIn
/[username] -> The public profile generated by a user

I have setted up the scope: "https://myapp.com/" and the start_url: '/pro in the pwa manifest settings at nuxt.config.ts. Althougt this settings when the PWA is installed still shows / as the main page. Is there something I'm doing wrong or there is some error in the module.

NOTE: In the /pro page I have a middleware that redirects to /auth if no user is detected. Also, in the /auth page I have a middleware that if a user is detected the app wil navigateTo /pro.

Also, is there a way to exclude some routes to the pwa? I would like to exclude the /[username] route from the intalled pwa, leaving only the /auth and the /pro routes.

Thanks
