Login in to Web Source Programmatically

Hello guys !
Not sure if this is the correct category.
But I am user and trying to login via C# Program in to https://power.genscape.com/,
which is using Auth0 for their Login-Page (need to be inserted Email and Password).
Write me please if you have any useful code for this ?
I saw examples, where should be provided CLIENT_ID and CLIENT_SECRET, and Request returns some Authentication Information. Then we can request a Token…
Probably you have a code for users to login ?
Thanks in advance !
