@IvesBertoli what kind of tag are you using and did you see the application output? "IsSupported" is false, so place some breakpoints and share the steps to see why it is false
this screenshot is result of another android app (https://play.google.com/store/apps/details?id=com.ssaurel.nfcreader).
@IvesBertoli I dont have the nfc tags that you are using unfortunately so I can't tell why you are facing this issue since our tags works fine for us.
As I asked before, when you were debugging: did you see the application output? "IsSupported" is false, so place some breakpoints and could share what is the reason that it is returning false?
I was having the same issue, after format the tag with NDEF format with another app (https://play.google.com/store/apps/details?id=com.manjul.utility.nfc.writer&hl=pt_BR&gl=US) it starts working. Is there a way to add a method for this ?

@dev-vinicius I dont have NFC tags of that type in order to test it, did you want to submit a PR with that functionality?
