Golden Visa - Non Property Route

Good afternoon,
Im looking into the Golden visa and all the information is geared to buying a property. Does anyone have any experience or know where I could get information on the "investment fund or venture capital fund" routes. How do these work and are they doable? Ive attached their description from the SEF website.

Many thanks
Andrew
