Commands lines should have existed since the release of the game, Apex is designed to have in game communication so you don't necessary need a mic. Some of the basic commands line would include:
1-Follow me.
2-Don't attack.
3-Stay behind me.
4-Stay in front.
5-Wait for me.
6-You need to heal/recharge your shield.
There are many more though but now you have an idea of what they are like and how important they are. Respawn should make this a priority since the game seriously need it.
