We were able to customize the (first) login screen of Universal using the custom.css as mentioned in replies within the community. This follow up question is about the second login page, when Thinkwise is being used as a passthrough to an external authentication provider. In our case these are AusweisApp (Germany specific) and eIDAS (European). The first page shows the company logo, company name and a continue button. After this a second page is shown where the OpenID Connect provider can be chosen (AusweisApp or eIDAS). Is it also possible to customize (use customer branding) on this second login page?
