I am trying to use the google static street view API to get an image of a property. The docs for the API state that I need to use a "digital signature": https://developers.google.com/maps/documentation/streetview/overview
I am trying to generate a signature, but the guide google provides doesn't seem to make much sense. These are the docs I am reading in regards to generating a signature: https://developers.google.com/maps/documentation/streetview/digital-signature#get-secret
But when I navigate to this page it doesn't seem to show the things mentioned in the docs that allow you to generate secrets.

When using Street View Static API or Maps Static API, the documentation specifically says:
Regarding your question, you seem to be on the Metrics page instead of the Credentials page.
Now on how to generate a digital signature, let me just quote the guide from the Documentation and add some additional details to help you.
Since your question is only about generating digital signature, you'll have to read the Documentation for more details and for the next steps.
Hope this helps.
