SCP using : style-src without 'unsafe-inline'

[JSON-stringify-24]

The official package can prevent this issue using css and js library separatly:

But unafortunatly this package only use sweetalert2.all.min.js provoking the next error:

sweetalert2.all.js:4283 Refused to apply inline style because it violates the following Content Security Policy directive: "style-src 'self' fonts.googleapis.com". Either the 'unsafe-inline' keyword, a hash ('sha256-47DEQpj8HBSa+/TImW+5JCeuQeRkm5NMpJWZG3hSuFU='), or a nonce ('nonce-...') is required to enable inline execution.
