For whatever reason, if you wish to unlink your Solana wallet address connected to the Safe Staker app, you can do so by using the /unlink-wallet command.
When you run the command, you have to use the wallet_address parameter to enter your linked wallet address to confirm unlinking.
NOTE - If you unlink your wallet:
Your active staking will cancel for that wallet.
To stake again, you will have to relink your wallet using the /link-wallet command.
