How to throw a grenade? (Far Cry 5)

Just bought the game. Can't understand how to use explosives: neither a grenade nor the other. My algorithm is: push L1->choose in the selector arms, I need vzrychatku( pereschelkivaya press L). and then what? if I had a gun , then he and remains. all the buttons pressed - grenade and not throwing. explosives not installed.
what am I doing wrong?
how to? what kind of algorithm?
similarly, throwing knife and so on
