Ordering of links at node

GoJS

@walter Thank you very much for your help, I have left the code to delete or modify as follows,

diagram.addModelChangedListener((evt: go.ChangedEvent) => {
    if (!evt.isTransactionFinished) return;
    const txn = evt.object;  // a Transaction
    if (txn === null) return;

    txn.changes.each((e: go.ChangedEvent) => {
      // record node insertions and removals
      if (e.change === go.ChangeType.Property) {
        if (e.modelChange === "linkFromKey") {
          console.log(`${e.propertyName} changed From key of link: ${JSON.stringify(e.object)} from: ${e.oldValue} to: ${e.newValue}`);
        } else if (e.modelChange === "linkToKey") {
          console.log(`${e.propertyName} changed To key of link: ${JSON.stringify(e.object)} from: ${e.oldValue} to: ${e.newValue}`);
        }
      } else if (e.change === go.ChangeType.Insert && e.modelChange === "linkDataArray") {
        console.log(`${e.propertyName} added link: ${JSON.stringify(e.newValue)}`);
      } else if (e.change === go.ChangeType.Remove && e.modelChange === "linkDataArray") {
        console.log(`${e.propertyName} removed link: ${JSON.stringify(e.oldValue)}`);
        const removedLinkData = e.oldValue;
        const existingLinkIndex = mappingLinks.findIndex(link => link.from === removedLinkData.from && link.to === removedLinkData.to);
        if (existingLinkIndex > -1) {
          mappingLinks[existingLinkIndex].deleted = true;
        } else {
          const removedMappingLink: MappingData = {
            from: removedLinkData.from,
            to: removedLinkData.to,
            config: configId,
            deleted: true
          };
          mappingLinks.push(removedMappingLink);
        }
      }
  });
});

const handleSave = async () => {
  if (mappingLinks.length > 0) {
    try {
      const linksToSave = mappingLinks.filter(link => !link.deleted);
      console.log('links a GUARDAR', linksToSave)
      const linksToDelete = mappingLinks.filter(link => link.deleted);
      console.log('links a ELIMINAR', linksToDelete)
      if (linksToSave.length > 0) {
        await $treeMapperApi.saveMappingLinks(linksToSave);
        alert('Mapping saved successfully');
      }
      if (linksToDelete.length > 0) {
        await $treeMapperApi.deleteMappingLinks(linksToDelete);
        alert('Mappings deleted successfully');
      }
      mappingLinks.splice(0, mappingLinks.length);
    } catch (error) {
      console.error('Error saving mapping links:', error);
      alert('There was an error saving the mapping');
    }
  } else {
    alert('There are no links to save');
  }
};

I would like you to help me with the context menu part for this tree mapper, the idea is that when I right click it opens the option to change the order, is this possible? I await your comments.
