Upgradesave place to store the logic hook / trigger

Hello,

I’ve got my logic file unter:

/custom/modules/mymodule/logic.php

If I call the logic hook from:

/custom/modules/logic_hooks.php

everything is working smoothly. But that file reads:

So where am I supposed to put my logic hook file?
If I place it in:

/custom/modules/mymodule/Ext/LogicHooks/logic_hooks.php

my code won’t be executed.

Any idea what I’m doing wrong here?
