I know this is presumably because of you using konsole's tabs as a part of your existing workflow, so it fits in there, but have you considered using helix' multi buffer system? It is described here : https://helix-editor.vercel.app/usage/buffers
To get tabs to show up, you have to enable the so-called bufferline:
:set bufferline always
It shows the name of the file and is well integrated.
