No, 'thumbs up' is an idiom meaning approval or good job, and is signed by simply making a thumbs-up gesture. The sign for 'thumb' is specifically for the physical body part.
You should use your dominant hand to do the pointing or tapping, while your non-dominant hand acts as the stationary reference point. This follows the standard ASL rule for active and passive hands.
A single, deliberate point or a quick double tap is sufficient. The primary goal is just to clearly identify the thumb, so a simple, clear indication works perfectly.
