JQ does not process part of the data

I can simplify the question by providing a link to the source data:

curl -sX GET "https://platform-explorer.pshenmic.dev/dataContract/GWRSAVFMjXx8HpQFaNJMqBV7MBgMK4br5UESsB4S31Ec/documents?page=23&limit=4" | jq -r .resultSet

At the end of the code, you can change the value of "limit", which will determine how many blocks are output. There are more than 1,000 blocks in total, and I need to extract the "label" and "timestamp" information for each block.`Inside there are identical blocks that contain the raw data for the "data" key.

{"identifier": "BVC9GYvsAwswBTfv4C2eziRZmZ6fUzrmMuvqv1VPdWG3","dataContractIdentifier": "GWRSAVFMjXx8HpQFaNJMqBV7MBgMK4br5UESsB4S31Ec","revision": 1,"txHash": "03CFE8DAB06ECCCDB1430F149041775263F85DF335046C0421449AA73A46B4DA","deleted": false,"data": "{\"label\":\"BFWookie\",\"records\":{\"identity\":\"Ea8acQwhQbbdaTLytoTiedEkTA89A8dyFpn9jTivr4Ht\"},\"preorderSalt\":\"hwebwVCxW+MwBmIqhoYIibGd7s7GOihv+MU6ae8Jj70=\",\"subdomainRules\":{\"allowSubdomains\":false},\"normalizedLabel\":\"bfw00k1e\",\"parentDomainName\":\"dash\",\"normalizedParentDomainName\":\"dash\"}","timestamp": "2024-10-23T05:40:07.923Z","isSystem": false,"owner": "Ea8acQwhQbbdaTLytoTiedEkTA89A8dyFpn9jTivr4Ht"}

I need to convert the data from the "data" key into the correct format :

{"label": "BFWookie","records": {"identity": "Ea8acQwhQbbdaTLytoTiedEkTA89A8dyFpn9jTivr4Ht"},"preorderSalt": "hwebwVCxW+MwBmIqhoYIibGd7s7GOihv+MU6ae8Jj70=","subdomainRules": {"allowSubdomains": false},"normalizedLabel": "bfw00k1e","parentDomainName": "dash","normalizedParentDomainName": "dash"}

I obtained the last one by processing the data from the "data" key using the following command :

echo  "{\"label\":\"BFWookie\",\"records\":{\"identity\":\"Ea8acQwhQbbdaTLytoTiedEkTA89A8dyFpn9jTivr4Ht\"},\"preorderSalt\":\"hwebwVCxW+MwBmIqhoYIibGd7s7GOihv+MU6ae8Jj70=\",\"subdomainRules\":{\"allowSubdomains\":false},\"normalizedLabel\":\"bfw00k1e\",\"parentDomainName\":\"dash\",\"normalizedParentDomainName\":\"dash\"}" | jq

But how can this be done quickly during the first data processing stage?Or another option?
