[MCU] How would Hela have gotten back to Asgard if Loki hadn't screwed up and opened the Bifrost?

Asgard can be reached by spaceship. Presumably any method of travelling such as the sling rings the sorcerers have will work. And agents of shield prove that can be replicated. So chances are hela was attack individuals and organisations which have tech/artefacts to allow travel and attempt to use one.
