[TYPO3-english] Hiding web submodule icon without disabling funtionality

[ktt]

Hello,

I created a backend module as web submodule. Now it appears in the left menu unde 'Web'.
Module mostly functions in background without direct interaction
via interface from user, therefore I would like to hide the icon in 'Web' list.
Is it possible to hide the icon without affecting functionality of the module?

Thank you in advance,
Kast
