Generate OG card here with my help because why not
There are two ways you can use this:

1. If you have the URL of the AsyncAPI document like this:

"https://studio.asyncapi.com/?base64=eyJhc3luY2Fwa..."

Go to: /api/og?docurl={link_of_your_doc}

2. If you have the base64 link of the AsyncAPI document, then

Go to: /api/og?base64={base64}
