Integrate Music Option for IG

For a client i need to have the MUSIC option on Instagram ready to be used in POSTS on the grid. Some of my accounts have the feature but some dont.

I need you to help me having this feature available on 5 IG accounts, either by telling me what to do or logging in. Also i need you to create 3 Instagram accounts with names i give you that i can then log in later.

THanks!
