The ethos wallet tool will not work. It brings up the wrong wallet addresses.
I have been in contact with FLX wallet. Waiting for reply from them.
I was able to pull up all other private keys on the FLX wallet using a bip39 tool on github.
I also edited the parameters in the ethos tool and brought up different addresses. I did try to get the parameters from FLX one people.
If I get the private key for the wallet I will probably do a 500$ challenge for someone to come up with an export tool to a Shelly wallet.
