UI Builder: "Link To Destination" and "NAV_ITEM_SELECTED" Events Not Working for New Records.

[DEV 1]

Description:
I am working on a UI Builder page where I need to redirect users from a subpage (e.g., "kb_view") back to the record page (e.g., "incident") when a specific action occurs. This works for existing records but not for new records where the sys_id is in the format "-1_u_1".

What I Tried:

1. Using "Link To Destination":
   Attempted to configure navigation via "Link To Destination," but it does not work for new records.
2. Using the NAV_ITEM_SELECTED Event:
   Below is the script I used:
   
   const redirectPayload = {
3.     redirect: true,
4.     route: "record",
5.     fields: {
6.         table: "incident",
7.         sysId: api.state.parentTabRecordId, // sys_id of the new record
8.     },
9. };
10. // Emit navigation event to redirect the user to the incident record
11. api.emit("NAV_ITEM_SELECTED", redirectPayload);
    Unfortunately, this also does not work for new records.

Goal:

I need a reliable way to redirect users from the "kb_view" subpage back to the "record" page, regardless of whether the sys_id belongs to an existing record or a new record (e.g., "-1_u_1").

Questions:

1. Is there a specific configuration or workaround to handle navigation for new records in UI Builder?
2. Does NAV_ITEM_SELECTED support this use case, and if not, what alternative approach should I use?
3. How can I ensure compatibility for both existing and new records when using navigation events in UX client scripts?

Any insights or suggestions would be greatly appreciated.

Can we set up client-side communication between the record page and the KB sub-page, such that we can manipulate the field values on the record page from a button event on the KB page?

Here is the reference URL:

We aim to update the fields on the record page from the knowledge page. Is there any way to achieve this functionality?
