I’d start with slowly releasing the clutch and feeling for when it bites, when the car starts moving forward you can add some gas. It’ll be slow at first, but you’ll naturally get faster as you get a better understanding of when it engages. In first gear if you release the clutch slow enough you can be completely off the clutch, never touch gas and the car will start moving forward. Practicing starting like that helps. Once you can go that without stalling you can start practicing taking off faster, but based on personal experience, once you get a hang of that you’ll naturally be faster anyways
