Manually add flare claim message to my xrp address?

[DanielFJ]

My XRP is in a COINOMI wallet and they do not offer a easy way for me to add the ETH address for claiming my FLR tokens... I'm in control of everything needed like the 24 words mnemonic, bip39 password, private key, etc... How can I add the message to my address so I can receive the tokens when they drop? I'm a programmer, I have no problems using libraries in any programming language that can get the job done... Thank you for any help!

If you've got the XRP secret/seed that starts with the letter s you can go ahead and just use my tools. See here:https://github.com/SimpleXRPTools/SimpleXRPTools

If you've only got the private key, then maybe you can find something using Ripple-Lib. See here: https://xrpl.org/cryptographic-keys.html#private-key
