[thekid]

Example:

use com\amazon\aws\{ServiceEndpoint, CredentialProvider};

$runtime= (new ServiceEndpoint('bedrock', CredentialProvider::default()))
  ->using('bedrock-runtime.')
  ->in('eu-central-1')
;

$response= $runtime
  ->resource('/model/{0}/converse-stream', [$model])
  ->waiting(read: 600, connect: 4) // <-- here!
  ->transmit($context)
;
