Thanks, Nwada001, for this. Although I don't usually see this kind of signed message on this forum, it's mostly used with the Ian Coleman (as mentioned by CT) method. I hope this will also be accepted here @charles-tim and @LoyceV
Your seed phrase will generate the private keys. Import your seed phrase on Electrum, Sparrow, Specter or Bluewallet and use any of the wallet to sign a message.
If you still want to use iancoleman, you have to change the derivation path from BIP44 to BIP84 and you will see your address and the private key.

For security, do not use iancoleman online website, download the it offline to use on a word editor.

Oh, wow. It worked. The address is now the same after I changed it to BIP84. I've never tried that before. thanks Charles-Tim. I think I should use the blue wallet since it is available on mobile.
Although I also found this site
https://reinproject.org/bitcoin-signature-tool/#sign, which I can use to sign and verify messages, after signing the message and trying to verify it, the Bitcoin wallet address has again changed to the first one from the Ian Coleman site.
