How do I add Avalanche to my trust wallet?

How exactly can I integrate Avalanche into my Trust Wallet? I've been hearing a lot about its potential and would like to explore it further. Could you please guide me through the process step by step? Is there any specific requirement or prerequisite that I need to fulfill before adding Avalanche? Also, would it be safe to store Avalanche in my Trust Wallet? Could you elaborate on the security measures taken by the wallet to protect my assets? Additionally, are there any fees involved in adding Avalanche to my wallet? If so, how much are they approximately? Thank you for your assistance in this matter.
