How do I cancel a TokenPocket transaction?

As a cryptocurrency enthusiast, I've been exploring various wallet options and TokenPocket has caught my attention. However, I've encountered a situation where I need to cancel a transaction I've initiated through the wallet. Could you please elaborate on the steps involved in canceling a TokenPocket transaction? I've read that cryptocurrencies operate on a decentralized network, so I'm aware that canceling transactions might not be as straightforward as with traditional financial systems. Nonetheless, I'd appreciate any guidance you could provide to ensure I take the necessary steps to resolve this issue. Thank you in advance for your assistance.
