I don’t like you close the post when you answer to it . In 20 years of job, I never saw that,?It is the user who can close the post when he think so !!
I resolve the post once I feel it has been properly replied to. This is because it has a negative impact on the plugin’s ranking in WP.org’s search results when forum posts are left open for too long.
none Gutenberg block need admin rights, only yours and if you agree to the above remark , the API KEY is not in the block , only ISBN with normal rights.
I will consider reinstating the ISBN field for all user roles, however, it probably won’t be for a few weeks. I would like to reiterate that the automated functionality for fetching the results from the Google Books API will still only work for admins.
And I’m marking this as resolved because I feel that I’ve adequately replied to your questions that directly relate to this plugin.
