Is Emmanuel Macron building a luxury bunker "in preparation for World War III"?

A viral post on social media claims Emmanuel Macron is spending almost 150 million euros in State funds on a luxury underground bunker to "shield the French elite from a looming World War III". The video claims to have solid proof coming straight from Tracfin, a service of the French Ministry of Finances that fights money laundering. In reality, this fake news probably comes from a Russian covert influence network called Storm-1516.
