Pathfinder 2 Grabbed Condition
You can find Conditions Rules here.
You’re held in place by another creature, giving you the flat-footed and immobilized conditions. If you attempt a manipulate action while grabbed, you must succeed at a DC 5 flat check or it is lost; roll the check after spending the action, but before any effects are applied.
