How to unveil riven?

[iLinlinn]

I'm quite new, i've been doing the challenges but it didn't unveiled. Some say you have to wear the mods first and some say you don't have to. I'm literally confused

Wear the mods first and then do the challenges. That's how it works.

Put the mod on any weapon of its type (rifle, pistol, etc), hover over the mod and read what exactly you're supposed to do to unveil it, bring the weapon into a mission, do the riven's challenge

You don't have to actually kill anything with that weapon, just have it with you, and you can complete or abort the mission whenever it says unveiled

Let your imagination loose with the challenges because there are many ways to cheese them. For example "While solo" challenges are not automatically failed when a player join your mission. Your friend can help you and leave the mission just before it is completed and the game considers you alone when you reach Extraction point.

You always have to wear a riven mod to unveil it, out of curiosity what do you think tells you you don't have to?

Once you wear the rivven mod on a dedicated weapon and in the mission :
You are aware of it's working when you enter the mission with the rules given center of your screen
You can still check your advancement when pressing pause/ menu/ start button...

You don't have to kill or do with the weapon modded with riven you want to unveiled.
Perhaps you confusion come from that
