Hi, how can i set custom headers when

Hi, how can i set custom headers when downloading a file via presigned url?

I tried setting it like this:

async function generatePresignedUrl(objectKey, endpoint, bucket) {
    const url = new URL(`${endpoint}/${bucket}/${objectKey}`)

    url.searchParams.set('X-Amz-Expires', '3600')

    const signed = await r2.sign(new Request(url, {
        method: 'GET'
    }), {
        headers: {
            'Content-Disposition': 'attachment; filename=' + objectKey
        },
        aws: {
            signQuery: true
        }
    })

    return signed.url
}

async function generatePresignedUrl(objectKey, endpoint, bucket) {
    const url = new URL(`${endpoint}/${bucket}/${objectKey}`)

    url.searchParams.set('X-Amz-Expires', '3600')

    const signed = await r2.sign(new Request(url, {
        method: 'GET'
    }), {
        headers: {
            'Content-Disposition': 'attachment; filename=' + objectKey
        },
        aws: {
            signQuery: true
        }
    })

    return signed.url
}

But I keep getting Signature Mismatch errors.

Can I set this via meta data when uploading a new file to r2?

I need to set this somehow, because e.g. Chrome always changes the fileextension of a custom zip extension to .zip
