Configure office365 on Google work

I have google for work account that I want to configure office 365 inside my domain. I have google admin account for my domain, but I dont know how to complete the setup. I'm stuck on the screenshot shown. If someone has done this before, he can go through the required steps with me in half to 1 hour to complete the Set up of SSO via SAML for Microsoft Office 365. The problem i face is I cannot connect my admin account in google to office365 application, so users will be able to have licenses by the email (example: user[at][login to view URL]) will have office365 licenses (word, powerpoint, teams...etc.) inside the office365 admin account. The error I get in [login to view URL] is OATH2 error. Reading support documentation shows I need to make a custom SAML app that connects to office 365 and autoprovision both accounts. I dont know if it's true, thats any I need someone who has done this sort of configuration using anydesk. Thanks,
