Passing in username/password/totp through CLI is ignored

[podpah]

Hey so I'm trying to set up saml2aws to be able to fill in my details from CLI so I don't have to set them in the browser. I use Bitglass authenticated via Jumpcloud and when I try to login I get the following:

op run -- saml2aws login --skip-prompt
Using IdP Account default to access Browser https://portal.bitglass.com/sp/silent/<>/?username=$<concealed by 1Password>&continue=/idp/init/<>/
Authenticating as <concealed by 1Password> ...

And then it opens the Browser and still asks me to put in my details to log into JumpCloud, even though I've provided them already. Also just a note that I'm providing them through the 1Password plugin with the SAML2AWS mfa_token, username and password variables set but I've also tried to provide them manually and still opens up Jumpcloud for me without logging in, for example:

saml2aws login --mfa-token=<totp>
Using IdP Account default to access Browser https://portal.bitglass.com/sp/silent/<>/?username=$<email>&continue=/idp/init/<>/
? Username <email>
? Password *************
Authenticating as <email> ...
INFO[0008] opening browser                              

And then it still opens up the browser and prompts me for all my details. Is it not possible to do because bitglass redirects auth or am I missing something?
