How to reset app config?

I want to use the user_saml app. I have already enabled it and I chose the SAML option not on purpose. How can I revert my choice? There is no button to do that and I cannot find where the apps settings are.

I found the answer myself. All apps settings are in the database, in the oc_appconfig table.
To reset the user_saml app and get the wizard again, I manually removed all lines for user_saml app except “enabled”, “installed_version” and “types”.
