Thor Ragnarok has a lot of plot holes regarding the Bifrost, like Hela not using the space stone to open portals to other worlds or using Odin's spear. I was rereading the thread when I saw this, but what plot holes are you talking about? The only time Hela moved between worlds/dimensions was in two instances:


 * 1) When she was freed from her prison, which was bound with Odin's life force
 * 2) When she hitchhiked to Asgard when Thor called for the Bifrost, which was opened by Skurge.

Other than that, she spent most of the movie in Asgard. It was her plan to use the Bifrost to conquer the Nine Realms again, yes, but that was stopped by the Revengers. Also, while I'm sure Gungnir could open the Bifrost, it's never explicitly shown to do so. Loki sending the Destroyer could have been assisted by someone acting in Heimdall's place since it's been shown that other Asgardians can take up his post in his stead
