Firebase.h not found (FCMPlugin.m)

Hello everyone, I hope you are well!
I’m building an ionic APP using the FCM plugin on IOS, but when I send it to xcode I get the message Firebase.h not found in FCMPlugin.m, I checked on the internet that I have to install the dependencies via pod but when performing the installations the error still continues, does anyone know how to solve this.
My Xcode version is 12.4 and cordova-ios 6.0.1
Ionic CLI : 5.4.16 (/usr/local/lib/node_modules/ionic)
Ionic Framework : @ionic/angular 5.5.2
@angular/cli : 10.0.8
