Is there a way to inject shell commands (NodeRuntime.runMain) executions as static variables?

export class ContainerRuntimeConfig extends Effect.Service<ContainerRuntimeConfig>()("ContainerRuntimeConfig", {
  effect: Effect.gen(function* () {
    //const containerRuntime = (container: 'podman' | 'docker') => Command.make(container, '--version').pipe(Command.exitCode);

    let test = yield* Command.make('podman', '--version').pipe(Command.exitCode)
    if (test) {
      return 'podman'
    }

    test = yield* Command.make('docker', '--version').pipe(Command.exitCode)
    if (test) {
      return 'docker'
    }

    return yield* Effect.fail(new Error('no container runtime on this machine'))
  }),
}) { }

Type 'Effect<"podman" | "docker", Error | PlatformError, CommandExecutor>' is not assignable to type 'never'. tsserver (2769) [11, 3]
