How to debug error "No render mappings found for MVC render command name"

I'm develpoping a module for my Liferay DXP and I'm struggeling with calling my renderCommands.

Following error message occurs on the initial render and whenever I try to click a link to my RenderCommand:

No render mappings found for MVC render command name "/document-management/document/edit" for portlet com_company_tools_manager_documents_web_portlet_DocumentsPortlet

I have my "view.jsp" which contains the inclusion of my "init.jsp", creation of renderURL and the link:

<%@ include file="./init.jsp" %>
    
    <portlet:renderURL var="editDocumentURL">
        <portlet:param name="mvcRenderCommandName" value="<%=MVCCommandNames.EDIT_DOCUMENT %>" ></portlet:param>
    </portlet:renderURL>
    
<a href="${ editDocumentURL }">edit documents</a>

The "MVCCommandNames.EDIT_DOCUMENT" refers to MVCCommandNames.java:

package com.company.tools.manager.documents.web.constants;

public class MVCCommandNames {
    public static final String EDIT_DOCUMENT= "/document-management/document/edit"; }

I'm including the file in the "init.jsp" like so:

<%@ page
    import="com.company.tools.manager.documents.web.constants.MVCCommandNames"%>

Finally, I have this "EditDocumentMVCRenderCommand.java" which should be seen as a component and be connected to the link:

package com.company.tools.manager.documents.web.portlet.action;
import com.company.tools.manager.documents.web.constants.DocumentsPortletKeys;
import com.company.tools.manager.documents.web.constants.MVCCommandNames;
import com.liferay.portal.kernel.portlet.bridges.mvc.MVCRenderCommand;
import org.osgi.service.component.annotations.Component;

@Component(immediate = true, property = { "javax.portlet.name=" + DocumentsPortletKeys.DOCUMENTS,
        "mvc.command.name=" + MVCCommandNames.EDIT_DOCUMENT}, service = MVCRenderCommand.class)
public class EditDocumentMVCRenderCommand implements MVCRenderCommand { (...) }

The portlets name which is called by "DocumentsPortletKeys.DOCUMENTS" is defined by

package com.company.tools.manager.documents.web.constants;

public class DocumentsPortletKeys {

    public static final String DOCUMENTS= "com_company_tools_manager_documents_web_portlet_DocumentsPortlet";
}

Did I forget to connect some things? How can I find out which URL the "EditDocumentMVCRenderCommand.java" listens to? Any other suggestions on how to approach this issue?
