How to refer to a project from innersource?

I have a java-maven project working on my STS. The thing is that I want to create my own spring-boot starter and include it as a maven dependency in the pom.xml file of my project. The thing is that this starter will be located in an innersource repository and I don't know what information I need to put in the pom.xml file to refer to that one in innersource and not to other one. Maybe is it possible to specify the URL of the repository or what?

Thanks you so much for your help!
