I'm testing the latest snapshot, but Gradle cant seem to find it

plugins {
    kotlin("jvm") version embeddedKotlinVersion
    id("org.jetbrains.compose") version "v1.0.0-beta6-dev462"
}
repositories {
    google()
    mavenCentral()
    maven("<https://maven.pkg.jetbrains.space/public/p/compose/dev>")
}

org.gradle.internal.exceptions.LocationAwareException: Build file '/home/elect/IdeaProjects/app1/build.gradle.kts' line: 5

Plugin [id: 'org.jetbrains.compose', version: 'v1.0.0-beta6-dev462'] was not found in any of the following sources:

- Gradle Core Plugins (plugin is not in 'org.gradle' namespace)

- Plugin Repositories (could not resolve plugin artifact 'org.jetbrains.compose😮rg.jetbrains.compose.gradle.plugin:v1.0.0-beta6-dev462')

Searched in the following repositories:

Google

Gradle Central Plugin Repository

maven(https://maven.pkg.jetbrains.space/public/p/compose/dev)

Am I missing something obvious? Snapshot is there, maybe some problem with the marker?
