How to extract information from other tabs?

For example, this product has 3 tabs, I can only extract information from the 'Description' tab and 'Downloads' & 'Specifications' are unreachable.

@dvz Normally, this can be achieved by using an 'Element click' selector for each of the available tabs, however in some cases, this data is natively embedded within the page HTML, therefore the use of an 'Element click' selector might be redundant.
