Access refused to Bedrock model

Hello, I've been granted access to Bedrock Titan Text G1 Lite model, as shown in the screen copy below:

However, trying to connect a client, as follows:

private final BedrockRuntimeAsyncClient client = BedrockRuntimeAsyncClient.builder().region(Region.EU_WEST_3).create().build();

using amazon.titan-text-lite-v1 as a model ID, raises the following exception:

Model invocation failed: java.util.concurrent.CompletionException: software.amazon.awssdk.services.bedrockruntime.model.AccessDeniedException: You don't have access to the model with the specified model ID. (Service: BedrockRuntime, Status Code: 403, Request ID: 6574c707-1378-4acd-98d0-ea794134acd7)
