 If needed, you can define the following project variable in your app’s `variables.gradle` file to change the default version of the dependency:
 
-- `$okhttp3Version` version of `com.squareup.okhttp3:okhttp` (default: `5.3.2`)
+- `$okhttp3Version` version of `com.squareup.okhttp3:okhttp` and `com.squareup.okhttp3:okhttp-brotli` (default: `5.3.2`)
 - `$zip4jVersion` version of `net.lingala.zip4j:zip4j` (default: `2.11.5`)
 
 This can be useful if you encounter dependency conflicts with other plugins in your project.
