Tutorial shows a Scissor Icon (not showing)

I am a newbie, I just installed Kdenlive and I watched YouTube tutorials. I am unable to display the scissor icon.

Which version of kdenlive you are running?
Which operating system are you using?

Thank you for your prompt response. I am using Version 5.15.12 (Built against 5.15.12) Windows. I expect the scissor tool icon to be used in an improved version and would like to update it if possible. I have learned to use the app without the tool icon.
