如何将CyberArk SAML认证的PowerShell代码转译为Python？

我需要对CyberArk Password Vault应用执行SAML认证，CyberArk提供的PowerShell代码可成功获取SAML Response令牌以进行后续调用，但目前无法将该代码复刻为Python实现。我最初尝试使用Selenium搭配Edge驱动，但未成功获取SAML Response。PowerShell代码并未使用特定浏览器，请问该如何将其复刻为Python代码？

可成功获取IDP的SAML Response令牌的PowerShell代码 #

我尝试过的Python代码（使用Selenium） #

这段代码会在自动化Edge浏览器中弹出MFA提示，但无法像PowerShell代码那样获取SAML Response。我是否需要不通过Edge浏览器，而是用通用框架打开IDP URL并处理SAML重定向？
