Can I buy Gala on Ledger?

Excuse me, I'm just getting started in the world of cryptocurrency and I'm a bit confused. Could you please clarify something for me? I've been hearing a lot about Gala and I'm interested in investing in it. But I'm using Ledger as my hardware wallet. My question is, can I buy Gala directly on Ledger? Or do I need to go through another platform first and then transfer it to my Ledger? I'd really appreciate it if you could explain the process to me step by step. Thank you!
