How do I add SUI to my Ledger?

Could you please guide me through the process of adding SUI tokens to my Ledger hardware wallet? I'm quite new to this and would appreciate a step-by-step explanation. Is there a specific app or contract address I need to install or add to my Ledger device? And, is there any safety precautions I should take while doing so to ensure the security of my funds? Thank you in advance for your help.
