Little snippet to generate a "siteid" for rclone when adding a sharepoint drive as a remote

sharepoint_id.js

const pageContext = _spPageContextInfo

const portalName = new URL(pageContext.webAbsoluteUrl).host
const siteId = pageContext.siteId.replace('{', '').replace('}', '')
const webId = pageContext.webId.replace('{', '').replace('}', '')

const resultId = `${portalName},${siteId},${webId}`

window.prompt(`Copy this id and use it in rclone`, resultId)

/* NOTE:
 * You must paste this in the console when in the main page of a sharepoint site.
*/
