How to activate the WTMSIG_BLOCK_SIGNATURES protocol feature?

I used :

$ curl --request POST --url http://127.0.0.1:8888/v1/producer/schedule_protocol_feature_activations -d '{"protocol_features_to_activate": ["299dcb6af692324b899b39f16d5a530a33062804e41f09dc97e9f156b4476707"]}'
{"code":500,"message":"Internal Service Error","error":{"code":3250000,"name":"protocol_feature_exception","what":"Protocol feature exception","details":[{"message":"protocol feature requires preactivation: 299dcb6af692324b899b39f16d5a530a33062804e41f09dc97e9f156b4476707","file":"producer_plugin.cpp","line_number":1191,"method":"schedule_protocol_feature_activations"}]}}

Also, I tried:

$ cleos -u http://127.0.0.1:8888 push transaction '{"delay_sec":0,"max_cpu_usage_ms":0,"actions":[{"account":"eosio","name":"activate","data":{"feature_digest":"299dcb6af692324b899b39f16d5a530a33062804e41f09dc97e9f156b4476707"},"authorization":[{"actor":"eosio","permission":"active"}]}]}'

}

I need to activate this because :

The eosio.system contract and eosio.bios contract can now only be
deployed on an EOSIO chain that has activated the
WTMSIG_BLOCK_SIGNATURES protocol feature.

But I’m not sure about the second approach as no contract has been deployed to eosio, how is it using action?

How can I activate it?

Any guidance is welcome.
Thank you
