Typescript target warnings after Angular 15 update

I updated my angular app to Angular 15. It builds ok - unless some warnings like:

TypeScript compiler options "target" and "useDefineForClassFields" are set to "ES2022" and "false" respectively by the Angular CLI.
​

My tsconfig.json sets the target to ES6:

{
...
"compilerOptions": {
"target": "ES6",
...
}
}


The documentation says:

Internally the Angular CLI now always set the TypeScript target to ES2022 and useDefineForClassFields to false unless the target is set to ES2022 or later in the TypeScript configuration.

And my .browserslistrc looks the same for month with no changes since the beginning:

last 1 Chrome version
last 1 Firefox version
last 2 Edge major versions
last 2 Safari major versions
last 2 iOS major versions
Firefox ESR


Thus, how can I get rid of this warning?
