Edit settings through the 'Settings' menu as you like.
This plugin changes the WordPress’s native formatting rules to keep the numbers of the line breaks you wrote.
It adds

You can change the settings below in the admin panel. For example: you can choose to add
tags for wrapping the paragraphs or not.
You can choose settings below.

This doesn’t work if you choose “none” in option #3.
Default is only “caption” but you can set multiple shortcodes separating “|”. Ex. “caption|map”
This plugin doesn’t work with the Visual Editor, so far.
