Support for the experimental syntax 'classPrivateProperties' isn't currently enabled #84

I enabled checkbox "ECMAScript 2022 (via babel-minify)" and get following error :

SyntaxError: unknown: Support for the experimental syntax 'classPrivateProperties' isn't currently enabled (2:3):

1 | class ClassWithPrivateField {

2 | #privateField; | ^ 3 | } 4 | 5 |

Add @babel/plugin-proposal-class-properties (https://git.io/vb4SL) to the 'plugins' section of your Babel config to enable transformation. If you want to leave it as-is, add @babel/plugin-syntax-class-properties (https://git.io/vb4yQ) to the 'plugins' section to enable parsing.
