Finding Maven coordinates for IntelliJ platform artifacts

I am refactoring common code used by multiple plugins into a library. The library needs to use IntelliJ platform classes, but I cannot figure out the correct Maven coordinates to put into my Gradle build file.

For example, my library needs the com.intellij.credentialStore.Credentials class. I'm loading com.jetbrains.intellij.platform:credential-store:<version>, as found at the IntelliJ repository, into my project, but the Credentials class does not exist in the package. Is there a way to find the Maven artifact that contains a given class definition?

Gradle build file:

plugins {
    id("org.jetbrains.kotlin.jvm") version "1.7.10"
    id("java-library")
}

repositories {
    mavenCentral()
    maven("https://www.jetbrains.com/intellij-repository/releases")
}

dependencies {
    val platformVersion = "221.6008.15"
    implementation(platform("org.jetbrains.kotlin:kotlin-bom"))
    implementation("com.jetbrains.intellij.platform:credential-store:${platformVersion}")
    implementation("com.jetbrains.intellij.platform:credential-store-ui:${platformVersion}")
    testImplementation(kotlin("test"))
}
