Changing Text 3D text through Custom event

Good afternoon

Can anyone help with the process required to change the text component of a 3D Text object when using a Custom Command? I am trying to use third-party software to change this text., which it does through Custom Commands.

I previously had this working nicely in UE 5.0. I did this through the ‘Set Text’ action in a blueprint. However, in UE 5.4, the ‘Set Text’ action for Text 3D objects seems to have been removed.

It remains for normal, 2D text, which continues to work correctly when being changed remotely by my third-party software. I have attached a screen shot of what the blueprint looks like for that.

I have also attached a screen shot of what I am currently trying for the 3D Text version. This isn’t working, so I assume I am doing something wrong somewhere.

Any help would be appreciated!
