It’s pretty cool, but I have trouble thinking of media where it takes a prominent role. The few examples that come to mind are:
Star Wars - The Force Mass Effect - Biotics/Element Zero technology Stellaris - Spiritualist Ethos Warhammer 40k - Psykers/Orks
What are some other examples of psionics in Sci-Fi?

They all communicate on a global channel and have to conceal it from the humans who are deeply distrusting of anything different.
