Adding partner using share function

I am trying to add my partner so he can access the lights we have set up. When I use the share function it states he doesn’t have an account with his email, he has signed in with Google, any suggestions?

Dear User,

Thanks for reaching out.
Currently, the sharing feature is not available for users who log in through third-party services (such as Google). We recommend sharing with users who registered using an email address.
Please feel free to contact us if you have any questions.

Best regards,
