How to secure access to DynamoDB in ReactJS?

Question

Amazon Web Services

Good afternoon.
I'm just starting to use AWS and learning ReactJS when the question came up.
We get a key to work with the database on Amazon.
After that, we can delete data from the database, add, execute any query.
Isn't it dangerous? After all, all JS code is visible in the browser.
All requests are visible. Those. getting the key is very easy and delete all data from the db.
How is it solved?
Thanks in advance for your clarification.
