Once we have added the multi-cameras in Shelf Builder, we need to make note of these names, then use the correct camera name to convert it into a base64 object.
make sure to change the shelf to the correct block name you are using in the shelf block
{ "shelf": {
"set:active_camera_name": "Camera_2"
}
}
Now we convert this object to bas64 using any online free converter, we will just use this for now:
Base64 Decode and Encode - Online
Once converted, we copy the new bas64 string to our respondent app publish url
eyAgICAic2IiOiB7CiAgICAgICAgInNldDphY3RpdmVfY2FtZXJhX25hbWUiOiAiQ2FtZXJhXzIiCiAgICB9Cn0=
We then add this bas64 to the url:
