Use general google credentials for Gmail node

The idea is:

Add a possibility to use the general Google oauth credentials for Gmail node, because there it is possible to set custom oauth scopes there.

An alternative would be to allow to customize the oauth scopes used in the Gmail oauth credentials.

My use case:

I want to narrow down the oauth scopes when when using Gmail node to only send emails.

I think it would be beneficial to add this because:

It is security best practice to use the narrowest oauth scope as possible.

Any resources to support this?

Are you willing to work on this?

Yes
