I have an additional domain name on my GSuite tennant. I want users to be able to log into the alternate email address/account on the GSuite by adding an additional button to their Apps page. The accounts are separate and can not be aliases.

If the accounts are completely independant, but in the same G Suite tenant, you can accomplish this by creating an additional G Suite tile in Okta. You'll want to make sure the username format matches the domain of these alternate accounts, and also set an appropriate name for the app to differentiate between the two tiles. When a user is assigned to multiple G Suite identities they would be able to choose which one to use by selecting the appropriate tile in the dashboard.
