I am aware that the dedicated bedrock server software does not inherently support experimental gameplay features. But there is a workaround that requires creating a world in minecraft with the experimental gameplay button toggled and then exporting it as an extracted zip folder to its respective location in the server folder. Upon doing this, only certain experimental features work, such as texture packs, functions, and more. However, custom items, recipes, blocks, or any custom behavior that isnt created with the vanilla game will not work.
