Exactly How Would I Make A Swinging/Grapple System Similar To AOT?

I’m currently trying to achieve a grapple system that allows the player to move freely while in air. This grapple system would be similar to Film’s Downfall (Downfall [Sandbox] - Roblox) and Typical Web Swinging Game ([GLIDING!] typical web swinging game - Roblox). I’ve looked at countless articles but I still can’t really find the answer I’m looking for. Help would be extremely appreciated. (Keep in mind that I’m new to simulating physics in Roblox)
