How to add server cert file

[EgHubs]

In the old repo, I made server cert in the following way
config.cert.file = "/firebaseCA.pem";
as the file was in SPIFFES files in ESP-32
the file was downloaded from this quote from the old library readme

The Google's GlobalSign R2 root certificate can be download from https://pki.goog/repository/

I can't find any example to make the same in the new library
I'm using the sync version.

You can set via the SSL client e.g. WiFiClientSecure::setCACert.

For reference, or anyone who needs to implement this
R2 doesn't work anymore!
nor R1 or GlobalSign R4
Only GTS Root R4 worked for me when I tried today!
Here is its download link
