Powerautomate with Adobe Sign (Initials + Signers)

Hi everyone,
In Powerautomate using the Adobe Sign connector, I am inserting 3 documents, which I can only include the signature, how can I include the "initials"


[
{
"memberInfos": [
{
"email": @{outputs('Compor_-_Email_Recursos_Humanos_Assinatura')}
}
],
"order": 1,
"role": "SIGNER"
},
{
"memberInfos": [
{
"email": @{outputs('Compor_-_Email_Colab')}
}
],
"order": 1,
"role": "SIGNER"
}
]
