I will check the documentation then. Thank you very much.

I have been enjoying most the kandance block, advanced gutenberg and atomic blocks. But I think they complement each other.

It depends on the plugin. You should ideally test this out on a local site to see what happens after uninstalling. Your block might get converted back to a basic paragraph block or even plain text. You can also try checking the documentation for the plugin you want to use, there should be something in there about this.
