The button text for Azure SSO should be changeable like it is e.g., with Gitlab.
Hello, maybe what you need is a custom SSO configuration instead of changing and existing button name.
Actually, they are testing Google SSO and have pending KeyCloak SSO integration (maybe you can use it to bind your custom SSO provider). You can check the roadmap here:
Also, it could be interesting to have a filed in the settings to name the button instead of showing “Custom SSO” or “Login with KeyCloak” for example. What do you think?
