Add PGP from protonmail

Hello all,

I'm trying to add PGP from protonmail to keybase...
Using these instructions: https://security.stackexchange.com/questions/151062/how-to-export-my-protonmail-private-key/151954

I managed to get:
- protonmail public key
- protonmail private key
- protonmail KeySalt
- protonmail KeyHash (password for private key)

I wanted to use the keybase method: "command line with [bash + GPG + cURL]"
Unfortunately, this method is not working for me...

I do not know how to create a valid PGP ".asc" file from (public key+private key+KeyHash)

(Because if I do not mistake, without the added set of keys in Linux. I can not verify the PGP key according to the chosen method in the Linux terminal)

Can you please advise me how to do it?

Start with linked issue #11893 and the referenced Keybase command-line method using Bash, GPG, and cURL. Compare the ProtonMail key material and requested import flow with the current documented behavior. Done means a supported, reproducible way to import and verify the ProtonMail keys, or a clear statement that this is unsupported.
