inside the quotation marks. You’re welcome.

Depends on who you ask. Like most "rules", there is not 100% agreement.
Me? Technical writer. People occasionally challenge me with some nonsense they learned in grammar school. Most of it is nonsense based on some morons in the late 1800s who thought themselves experts and tried to force rules onto a language that was affected by numerous things including the Norman invasion of England.
The salient thing to know about these morons? They wanted to impose rules from Latin onto English. Historically, it's all nonsense.
Associate Press style guide has lots of these nonsense "rules". Strunk and White's
Elements of Style is full of more nonsense. You'd be better served to, in general, write as you speak, because language is fluid and things that were right some time ago, no one cares about anymore, and this happens
all the time.
For example, not many people other than professional writers use "fewer" anymore. They use "less" for everything.
Technical writing is an interesting use of language. It is highly artificial, designed to use the fewest words to descibe something, eliminate as much metaphor as possible, and in a previous job, writing for an international audience.
Loved my grammar classes.
