This mod adds an item called the "Infinity Rocket". It will allow you to add one firework to your inventory at a time. A great way to use it is to have the item in your off hand with no item in the main hand. Then just double right click to get a boost. It's crafted using 4 Netherite Ingots, 3 Phantom Membrane, 1 Regular Firework and 1 Nether Star (see images). There is also an achievement for crafting one as well.
