Stack function not available on SNAP 7.0 for Ubuntu

I am new to SNAP and I have installed tha latest version downloaded from the European Space Agency.
I am following some tutorials and need to stack some bands but I am not able to find the stack function.


I should be findind the Create Stack function in the following place:
Radar > Coregistration > Stack Tools > Create Stack

But I don’t have the Radar tab either

In your screenshot it is at the third position in the menu.
Besides that, you can always search for tools via the text field in the upper right corner.
