This type of use falls under the exception in copyright law illustration for instruction.
It constitutes a low risk as long as it doesn’t compete with the product (for example, if the product owner were to sell separate videos on how to use the product, which usually is highly unlikely).
It’s no different from the many ‘How to’ videos you find on YouTube that don’t appear to be taken down.
Some software licences may even include permission to make copies/screenshots for user training purposes.
