I can't find or delete my working access tokens for R2

const s3 = require('@aws-sdk/client-s3');

const s3Client = new s3.S3Client({
    region: 'us-east-1',
    endpoint: process.env.S3_ENDPOINT,
    credentials: {
        accessKeyId: process.env.S3_ACCESS_KEY,
        secretAccessKey: process.env.S3_SECRET_KEY
    }
});
