how to change/add gpg key to pass

I need to change the gpg key originally used for **pass** on my system to a newly generated key. However, when I follow the advice I found on this thread: https://unix.stackexchange.com/questions/226944/pass-and-gpg-no-public-key , things don't seem to work out as they should. The command used and its output while trying to replace the original gpg key with an alternate gpg key was:

$ pass init -p .password-store GPG-id
mkdir: created directory '/home/naphelge/.password-store/.password-store'
Password store initialized for GPG-id (.password-store)
[master 8d65cea] Set GPG id to GPG-id (.password-store).
 1 file changed, 1 insertion(+), 1 deletion(-)

So the command seems to just be making a new dir, **.password-store** in the original dir **.password-store** and creating a new **.gpg-id** file with my new key's GPG-id in it, and not proceeding to re-encrypt all of the gpg files in **.password-store** with the new gpg-key. The same advice is provided in this thread regarding a similar goal as well: https://askubuntu.com/questions/929307/how-to-change-the-gpg-key-of-the-pass-password-store I noticed that in the original **.gpg-id** file in the **~/.password-store** dir that it is the original gpg-key's fingerprint (without spaces between the (10) 4 digit blocks) that is saved. So I did try the same command above, pass init -p .password-store FINGERPRINT-id, using the new key's fingerprint (without spaces), as well trying just specifying the email address associated with the key, pass init -p .password-store naphelge@email.com, to try and initiate the re-encryption of the gpg files in **.password-store** with the new gpg-key, but always with the same result. So I am not sure, looking at other posts and the pass man page what else to try to get this to work. Any suggestions or advice appreciated. Thks.
