Create a switch to be used in rules script

I have a rule with a blockly script where I need to check the state of a switch I created on OH.
The problem it’s that I can’t see this switch into Blockly, when i click to add item or thing the switch it’s not showed into the list, so probably I made something wrong… Anyone can told me the correct steps to create it?

I’m using OH3.2.0

Maybe the switch is “non-semantic” ? Check the box at the bottom of the selection window. Then it should appear.

Yes, I checked “show non-semantic” but still not showed.
