android studio, how to make signed apk for release build (gradle using KTS build files)

Question

Would like to run the release build (it is app with multiple lib modules), but it is asking for sign it.

was working by adding the code in the gradle file as:

android {
    signingConfigs {
        config {
            keyAlias 'key0'
            keyPassword 'test'
            storeFile file('/root/user/androidPrjsKeyStores')
            storePassword 'test'
        }
    }
    compileSdkVersion build_versions.target_sdk
    buildToolsVersion build_versions.build_tools
    defaultConfig {

but after the change the gradle to KTS build files, this code does not work.

so went through the way with android studio

and got t:

and

cannt open the project for fixing:
