Link should lead to our SEP platform

Sorry, I should've pointed out that promotions 2 and 3 should link to the panelist overview page: https://content.saberespoder.com/ofertas/Trabajo/como-ser-miembro-del-grupo-de-opinion-de-saberespoder

Promo 1 doesn't actually need to link anywhere since we're encouraging them to text us a question.

Is it possible to vary the links like that, or does every promotion need to link to something and/or the same place?

@stan2020 no worries, it doesn't really matter if promotion has to have a link or not – we can vary the links as we want
