[Hosted-Portals] Add more social media links to the footer

Dear all,

The base them has twitter and github as default social media, we try to add facebook and youtube following the default formula:

twitter_username: sibcolombia facebook_username: SibColombia github_username: SiBColombia youtube_username: sibcolombia

But it doesn't work, It keeps showing only twitter and github.

How can we add facebook and youtube or any other relevant social media links?

Thank you in advance,
