especially from marginalized communities

Shobita Parthasarathy, a social scientist at the University of Michigan in Ann Arbor, whose research focuses on equity in biomedical innovation, agrees. She wants to see equity baked into ARPA-H from the outset, and hopes Wegrzyn will do this by placing emphasis on community outreach and input, especially from marginalized communities, to determine which health problems to tackle.

I don't understand the use or function of the word "from" in "especially from marginalized communities".
It says "she hopes Wegrzyn will do this by placing emphasis on community outreach and input", so it seems to me that it should have been "especially for/on marginalized communities".
What does "from" mean there? A typo or a type of expressing a different meaning?

It's input from marginalized communities in particular.
