I figured it out. It's just like Skyrim lockpicking except you have to do it right for a sequence of 5 times in a row and if you get it wrong you gotta start from the beginning again.Well, it's be helpful if you make gamepad keys with compiring on keyboard. Because it's that difficult blocking me how to strugle.
I don't think you have to go into the inventory and click the item to start struggling, but either way you enter struggling mode by holding shift.
As they said, there's three struggle position, down (S) , neutral (just hold shift without pressing anything), and up (W).
Once you're in one of those three positions, keep the position held and you struggle with (Q) and (E)
If you get the position correct, you'll hear an audio cue and a check mark, if wrong a cross and a "WRONG" buzzer sound.
get all in the sequence correct and the health bar of the tape will go down by a few points
if you get one wrong, you'll have to restart at the beginning of the sequence, but not the whole health bar
Repeat until the tape's health is depleted
One tip is don't mash your struggling
