How to use the sourcegraph.Location function in sourcegraph

location: { range, uri: uriFromLangServer },
}: {
    currentDocURI: string
    location: lsp.Location
}): sourcegraph.Location => {
    let definitionURI: sourcegraph.URI
    if (/^file:\/\/\//.test(uriFromLangServer)) {
        // The definition is in a file in the same repo
        const docURL = new URL(currentDocURI)
        docURL.hash = uriFromLangServer.slice('file:///'.length)
        definitionURI = new sourcegraph.URI(docURL.href)
    } else {
        definitionURI = new sourcegraph.URI(uriFromLangServer)
    }

    return new sourcegraph.Location(
        definitionURI,
        range &&
            new sourcegraph.Range(
                new sourcegraph.Position(range.start.line, range.start.character),
                new sourcegraph.Position(range.end.line, range.end.character)
            )
    )
}

const diagnostics: sourcegraph.Diagnostic[] = clones.map(c => {
                    const numLines = c.duplicationA.end.line - c.duplicationA.start.line
                    return {
