GMail authentication multi tenant to QlikSense SaaS

Hi Dear community

I’m a developer and architect solution engineer from a Qlik Partner Company, we have some customers with QlikSense SaaS, one of them, has the following requirement, that i want know if is possible solve with okta

The customer wants use mor than one IDP (GMail) with QlikSense SaaS, actually on QlikSense SaaS you can configure more than one IDP, but you only can active one at same time

The customer has two or three GMail authentication services, because has three different companies (each company has his own domain).

What is the idea, use okta to receive the authentication from any GMail account of two or three companies and then go to authenticate on QlikSense SaaS. On QlikSense SaaS we will be register and activate okta like active IdP
