Those videos look great Michael.
Her pushing the pot, knocking it with her feet, and even the vocalization are preferable as alerts to just visual contact, but you are right, she seems to be more questioning for confirmation. Notice how she also noses the other pots but doesn’t vocalize.
You are doing a great job. good timing and great impulses on when to wait.
Alerts constantly evolve and eventually you will get to the point where she will only be rewarded for a vocalization and a physical movement engaging the odor, but keep doing what you are doing! You also notice at one point she bows down in recognition of odor. This can also eventually be turned into a lie down at source. These are all great. Keep it up.
