unable to get the List of objects using Java Use API and Sightly(Htl)

I am trying to get a List of custom object of type linked list into html using Sightly. But I a unable to read them in sightly. Sample Code is pasted below:

Java Bean:

public class MiniNavBean {

private String fPath;
    
private String activeAttr;

public MiniNavBean(String fPath, String activeAttr){
        
        this.fPath = fPath;
        this.activeAttr = activeAttr;
    }

public String getFpath() {
        return fPath;
    }

    public void setFpath(String fpath) {
        this.fPath = fpath;
    }

    public String getActiveattr() {
        return activeAttr;
    }

    public void setActiveattr(String activeattr) {
        this.activeAttr = activeattr;
    }

}

Java class which extends WCMUsePojo:

public class MiniNav extends WCMUsePojo {

private List<MiniNavBean> navList;
   
MiniNavBean miniNav;
    
    public List<MiniNavBean> getNavList() {
        return navList;
    }

    public void setNavList(List<MiniNavBean> navList) {
        this.navList = navList;
    }

@Override
    public void activate() {

navList = new LinkedList<MiniNavBean>();

fPath = "fpaths";

activeAttr = "activeattrs;"       

miniNav = new MiniNavBean(fpath, activeattr);

navList.add(miniNav);

}

}

Html file (Sightly):

<div data-sly-include="/apps/project/components/global.jsp"></div>
<div data-sly-use.mininav="com.components.MiniNav" data-sly-unwrap>

<div data-sly-list.navlist="${mininav.navList}">
                <li>
                <p>${navlist.fPath}</p>
                <p>${navlist.activeAttr}</p>
                </li>

</div>

When I am trying to execute the above code, I am able to see the linked list getting instantiated with the data in the java class. However when I am trying to display the values of the list in the front end, sightly is unable to read it.

Since the LinkedList is of CustomObject type(MiniNavBean) I suspect sightly is unable to read it as it doesn't know about this bean because we didn't refer that bean anywhere. Is there a way to fix this using sightly tags and read the data ?
