Url Rewrite in web.config does not work

The problem I have is that I can not access the endpoint of my api correctly, it always returns a 404 or 403. The api is mounted with slim on a iis 8 and the structure is as follows:

My web.config is located in /v1/Web.config (at the end of the project in the image) and its code is as follows:

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
    <system.webServer>
        <rewrite>
            <rules>
                <rule name="rule" patternSyntax="Wildcard">
                    <match url="*" />
                    <conditions>
                        <add input="{REQUEST_FILENAME}" matchType="IsFile" negate="true" />
                        <add input="{REQUEST_FILENAME}" matchType="IsDirectory" negate="true" />
                    </conditions>
                    <action type="Rewrite" url="index.phk" />
                </rule>
            </rules>
        </rewrite>
    </system.webServer>
</configuration>

I need that when the user accesses the url link Go find the index.phk file inside the public folder, it does not matter if you call an endpoint or the root / v1, you should always go to find the index.phk file. Thank you for your attention.
