file schema.graphqls is not recognized as a grahql file

I'm trying to use graphql for the first time, and I have a problem with the schema.graphqls file, in fact the extension is not recognized even in my pom.xml I added the dependency :

<dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-graphql</artifactId>
</dependency>
