How do shields work compared with melee and projectiles?

In Overwatch, all melee goes through all shields (except for of course "bubbles" like Zarya which are act more like bonus health).

Is that the same for Marvel Rivals? Does it matter if it's a "quick melee" (i.e. "V" by default on keyboard) or a "melee autoattack" like any melee heroes (Thor, Cap, etc etc)?

Also, do shields block ALL non-melee? Does it vary in any way? For example in OW a shield can even block an earth shatter, or a grav, etc etc. it blocks literally everything but melee. Is that true for Marvel Rivals or does it vary?
