title: How to change clientId, authority values after MSAL has already read the configuration? [msal]
body: <p>I am using Azure AD B2C with a multi-tenant application. User first enters email, then a drop-down is filled based on the tenant he is related to (tenant1, tenant2, tenant3). The user selects tenant1 so he will be redirected to tenant1's custom login page(background and logo).</p>
  <p>So after the user selects the value in drop-down based on that API returns clientId_, authority_, postLogoutRedirectUrl_ I want to set these values to MsalModule.forRoot()_</p>
  <p>How can I achieve this? Please help !!</p>
