I'm using Node-RED to create an OPC-UA structure dynamically. Everything is working fine, but I noticed that the browseName is being appended to the NodeId when adding variables.

Here is how I'm adding a variable:

```
 messages.push({
     ...msg,
     payload: { opcuaCommand: "addVariable" },
     topic: `${variableId};browseName=${browseName};datatype=${opcuaType}`
});

```

And here’s what I see in Prosys OPC-UA Browser:

```
NodeId: ns=1;s=FESP_100140.Electricity.Phase1.ActivePower;browseName=ActivePower
BrowseName: 1:ActivePower
DisplayName: ActivePower

```

Expected Behavior:  
The NodeId should remain clean (ns=1;s=FESP\_100140.Electricity.Phase1.ActivePower), while browseName should only affect the display name and browsing behavior.

Questions:

- Is this the expected behavior in Node-RED's OPC-UA implementation, or is this a bug?
- Should browseName be passed differently in Node-RED OPC-UA?
- How can I properly set the NodeId and browseName separately without concatenating them?

Any insights or fixes would be greatly appreciated!  
Thanks in advance.
