GET sdkKey for join Meeting

I’m trying to access a Zoom session through the Web API in js, one of the data it asks for is the sdkKey, but when I create an application in the Zoom Marketplace nowhere I see the sdkKey. This is the object I have to use to start the session:

ZoomMtg.init({
leaveUrl: leaveUrl,
success: (success) => {
console.log(success)
ZoomMtg.join({
signature: signature,
sdkKey: sdkKey,
meetingNumber: meetingNumber,
passWord: passWord,
userName: userName,
userEmail: userEmail,
tk: registrantToken,
zak: zakToken,
success: (success) => {
console.log(success)
},
error: (error) => {
console.log(error)
},
})
},
error: (error) => {
console.log(error)
}
})

Can you help me?

@msdzoom4 ,

when you create a meeting sdk app type, you should be able to see Client ID and Client Secret. Use Client ID as your SDK Key
