How can I change the `AUTHORIZE ACCESS` button in a Google Apps Script based Google Workspace Add-On

I am develloping a Google Apps Script based Workspace add-on.

I am trying to figure out how to edit the AUTHORIZE ACCESS button to match Google's Sign-In Branding Guidelines.

I've searched high and low and don't see anything that talks about how to edit the sign-in experience for add-ons.

• The branding guidelines apply to buttons that you create yourself.
• The AUTHORIZE ACCESS button under the text

Would you like to give this add-on access to your account? This add-on would like to show additional information in Gmail, but it needs approval to access your Google account.

is a standard Google interface that typically appears when you test an Add-on deploying it from the Apps Script editor

• The above mentioned screen cannot be modified in any way, since it is being generated by Google.
• In any case, when an Addon is installed from Google Marketplace, opposed to being tested locally, the authorization prompt will occur in a pop-up window during the installation process, rather than within the sidebar of the Add-on.
