Can I buy Arweave on Ledger?

Could you please clarify something for me? I'm a bit confused about whether it's possible to purchase Arweave using Ledger. I've heard Ledger is a secure way to store cryptocurrencies, but I'm not sure if it also facilitates purchases. Is it possible to buy Arweave directly through Ledger, or do I need to use another platform for the purchase and then transfer it to my Ledger wallet for safekeeping? I'd really appreciate it if you could provide some clarity on this matter.
