BearSSL::WiFiClientSecure' has no member named 'loadCertificate'

When I try uploading the code into my WeMos D1 Mini board. It gives me the error below:

C:\Users\JakeNguyen\Desktop\ESP8266\mqtt_x509_DER\mqtt_x509_DER.ino: In function 'void setup()':
mqtt_x509_DER:117:17: error: 'class BearSSL::WiFiClientSecure' has no member named 'loadCertificate'

exit status 1
**'class BearSSL::WiFiClientSecure' has no member named 'loadCertificate'**

Im not sure how to fix this problem. If anyone has an idea how to fix it, please help me!

This code was initially designed for axTLS, so it has different APIs of BearSSL, but you can replace it using: setTrustAnchors and setRSACert

Like in this example: https://github.com/esp8266/Arduino/blob/da6ec83b5fdbd5b02f04cf143dcf8e158a8cfd36/libraries/ESP8266WiFi/examples/BearSSL_ServerClientCert/BearSSL_ServerClientCert.ino

Thank you for your response!
Would it be possible you can tell me where I can replace it in the code please? From the exam you gave it, can I just copy set TrustAnchors and serRSACert into the original code or I can copy the whole void setup() function?
