i have added the the certificates in src/cert folder

i have added below commands in platformio.ini file
board_build.embed_txtfiles =
src/cert/private.pem.key
src/cert/certificate.pem.crt
src/cert/aws-root-ca.pem


and also i have added below commands in the cmakelist.txt file
target_add_binary_data(${CMAKE_PROJECT_NAME}.elf "src/cert/certificate.pem.crt" TEXT)
target_add_binary_data(${CMAKE_PROJECT_NAME}.elf "src/cert/private.pem.key" TEXT)
target_add_binary_data(${CMAKE_PROJECT_NAME}.elf "src/cert/aws-root-ca.pem" TEXT)
