Codeigniter 4 CSP don't support style-src-attr

Hi, I have a problem to add style-src-attr 'unsafe-inline' rulle to CSP header. There is no "addStyleSrcAttr" function in CSP Library. 
Temporarily i solve this problem with my own custom CSP Library:

 ContentSecurityPolicy.php
// namespace App\Libraries;
.....
    public function addStyleSrcAttr($uri, ?bool $explicitReporting = null)
{
        $this->addOption($uri, 'styleSrcAttr', $explicitReporting ?? $this->reportOnly);
        return $this;
    }
....
    protected function buildHeaders(ResponseInterface $response)
    {
        // Ensure both headers are available and arrays...
        $response->setHeader('Content-Security-Policy', []);
        $response->setHeader('Content-Security-Policy-Report-Only', []);

        $directives = [
           ....
            'style-src'      => 'styleSrc',
            'style-src-attr'  => 'styleSrcAttr', // Added the new style attr
           ....
        ];

Apparently, the CSP3 directives are not implemented in CI4.

It would be helpful if you could send a pull request to add the directive to the 4.5 branch.

Hi Kenjis, thank you for info.
You are right there is no CSP3 support in CI4.
I must implement other CSP headers too, like:
script-src-attr, script-src-elem, style-src-elem... 

Sorry but I have no experience with sending a pull requests to CI, and actually I have al lot of work
If you have a time please help me and send this request to add CSP3 support.

Sorry for my bad English. 
Thank you.
