Minecraft Movie Building Challenge should be accessible to Java players

I'm on a device that can't run Minecraft Bedrock, and I want to be able to participate in the Minecraft Movie Build Challenge. However, due to the map being on Marketplace only and thus, Bedrock only, myself, along with other Java-only players can't participate in the challenge. At the moment, I do not have access to a device that can reliably run Minecraft Bedrock, and my device is unable to download Minecraft Marketplace to even get the map in the first place.
