How do you get the document id and workspace id of the currently active document and workspace

lcui

I wonder what is the best practice to get the did and wid of the currently active document? I'm developing an app in the side panel and currently I'm using some JS code like the following to help me get them:

function getDocumentInfo() {
  onshape.getDocument(function(documentInfo) {
    if (documentInfo && documentInfo.documentId && documentInfo.workspaceId) {
      const documentId = documentInfo.documentId;
      const workspaceId = documentInfo.workspaceId;

      console.log("Document ID:", documentId);
      console.log("Workspace ID:", workspaceId);

      redirectToPanel(documentId, workspaceId);

    } else {
      console.error("Could not retrieve Document ID and Workspace ID from Onshape.");
      // Handle error appropriately, maybe display a message to the user.
    }
  });
}

function redirectToPanel(documentId, workspaceId) {
  const panelUrl = `/panel/?documentId=${documentId}&workspaceId=${workspaceId}`; // Adjust the URL path if needed
  window.location.href = panelUrl;

// Call getDocumentInfo() when your side panel is loaded or when you need to get the IDs.
// For example, you might call it when a button is clicked in your side panel.
getDocumentInfo();

But I wonder if this is a common practice? Do you have a better way?
