Not getting the login page on csm portal but instance I'm still seeing the sso page for my login

[Rotimi Oladime1]

I'm having issues accomplishing to have the login page in the csm portal when I click on login, I have followed everything in these two documents carefully  https://support.servicenow.com/kb?id=kb_article_view&sysparm_article=KB0962488

https://support.servicenow.com/kb?id=kb_article_view&sysparm_article=KB0719767

I cloned the login widget and commented the line 81 on the server script 

//data.default_idp = GlideProperties.get("glide.authenticate.sso.redirect.idp");

I seem to have done everything correctly here but I'm still being redirected to my work login session instead of the customer login page on the csm portal when I put the instance url in the incognito browser page.. 

can anyone help me figure out what I might have missed here please?
