GKD and Custom Rules

I’ve been using https://github.com/gkd-kit/gkd for automating some repetitive tap/click tasks. Recently, I’ve encountered some scenarios not covered by my current subscriptions, so I want to customize my own rules. I mainly utilize the method described here: https://gkd.li/guide/snapshot#by-inspect to create custom rules. This process requires installing an extension that still uses Manifest V2. My current Chrome version is 140+, and I’m unable to install the extension. I get the following error:

Cannot install extension because it uses an unsupported manifest version.

I searched for a solution and found this workaround: stackoverflow

"/Applications/Google Chrome.app/Contents/MacOS/Google Chrome" --disable-features=ExtensionManifestV2Unsupported,ExtensionManifestV2Disabled

Problem solved!
