How do I add money to TokenPocket?

As a cryptocurrency user interested in diversifying my wallet options, I'm considering using TokenPocket. However, I'm unsure about the process of adding funds to this wallet. Could you please guide me through the steps? Specifically, I'd like to know if I need to link my bank account, use a credit card, or if there are other methods such as cryptocurrency transfers. I'm also curious about any fees or limitations associated with depositing funds into TokenPocket. Additionally, I'd appreciate any security tips you have to ensure the safety of my funds within the wallet. Thank you for your assistance.
