Grails 7 - grails-spring-security Doc - Static Request Map

### Expected Behavior

I am following doc https://apache.github.io/grails-spring-security/7.0.x/core-plugin/guide/index.html section 4.5. Static Map. If i **don't add** securityConfigType line, everything works fine as expected.
`grails.plugin.springsecurity.securityConfigType = "InterceptUrlMap"`
then I add static rules
`grails.plugin.springsecurity.controllerAnnotations.staticRules = [ ... ]
grails.plugin.springsecurity.filterChain.chainMap = [ ... ]`
But if i **add** this securityConfigType line (as document says i should) i get _not authorized_ error.

### Actual Behaviour

when i add the line securityConfigType, i get not authorized. For example index page is permitAll but still I get _not authorized_.
`[pattern: '/assets/**', access: ['permitAll']],
[pattern: '/index', access: ['permitAll']],
[pattern: '/index.gsp', access: ['permitAll']],`
Confusing part is, /assets/ are permitted. This works http://localhost:8083/example3/assets/grails.svg but this is not authorized http://localhost:8083/example3/

### Steps To Reproduce

See my [Example3 config](https://github.com/arjangch/grails-project-helper/blob/main/example3/grails-app/conf/application.groovy)
Am i configuring this wrong?

### Environment Information

java=21.0.8-zulu
gradle=8.14.3
groovy=4.0.28
grails=7.0.0-RC2

### Example Application

https://github.com/arjangch/grails-project-helper/blob/main/example3

### Version

7.0.0-RC2

Reproduce the problem with the example3 application and inspect its grails-app/conf/application.groovy configuration alongside section 4.5, “Static Map,” of the Grails Spring Security 7.0.x guide. Compare behavior with and without securityConfigType set, focusing on why /assets/** is permitted while /index is rejected. Done means the example and documentation agree on the correct configuration and the index request is handled as documented.
