How to retrieve matic network account after reset

For some reason the iphone app today wont accept my faceid and the password associated with the acct (saved on my phone) is no longer working. I could use the seed phrase to recover, but i am slightly worried of subsequent issues. Mainly i had the matic network setup on there, i dont recall what if anything the public/private key for that was and from what ive read about resetting your account with seed phrase those networks would have to be added back manually.

my q is if i manage to recover my acct with seed phrase, how exactly will i go about recovering the matic network account?
