Url to the jupyterlab notebook

I have a use case, wherein i want to open a particular notebook in jupyterlab and just show that notebook and nothing else. I am able to create the url path for the notebook, eg lab/tree/.ipynb, however, sometimes i see jupyterlab shows 2 tabs with notebooks (which are located in the same location). Please look at the attached image for more clarity

Here the url was pointing to the notebook starting with c2f, however it had the workflow.ipynb tab also beside it.
Is it related to some session cookie? How can i fix this issue? One solution is to move to Simple view, which doesnt show multiple tabs, but i want to fix in the normal view, if possible.
