Hide drop-down translation menu on navbar for logged in members?

[furnivat]

Thanks for this excellent product. It is working well for me.

Could you help me with a smalll question please?
I want to hide the translation menu for logged in members. What code would I put in the navbar template please?

Actually ideally I would hide the drop-down translation menu only for members whose langauge preference is set to English. Is that possible, please?
