Delete photos, videos, and reviews from the Google Maps desktop site. Huge disclaimer: these will probably get out of date at some point and may not work. You should read and understand the code before you do anything with it.

photos.js

// delete photos from Google Maps
(async () => {
  const sleep = (time) => new Promise(resolve => setTimeout(resolve,time));
  const go = async () => {
    // click the kebab
    document.querySelector('button[jsaction*="pane.photo.actionMenu"]:not([aria-hidden="true"])').click();
    await sleep(200);
    
    // click the delete menu item
    document.querySelector('#action-menu div[role="menuitemradio"]').click();
    await sleep(200);
    
    // click the "yes I'm sure" button
    document.querySelector('div[aria-label="Delete this photo?"] button+button,div[aria-label="Delete this video?"] button+button').click();
    await sleep(1500);
    
    // check if there's any left, and do it all again
    if(document.querySelector('button[jsaction*="pane.photo.actionMenu"]:not([aria-hidden="true"])')) go();
  }
  go();
})()

reviews.js

// delete reviews from Google Maps
(async () => {
  const sleep = (time) => new Promise(resolve => setTimeout(resolve,time));
  const go = async () => {
    // click the kebab
    document.querySelector('button[jsaction*="review.actionMenu"]:not([aria-hidden="true"])').click();
    await sleep(300);
    
    // find the delete review menu item
    const deleteMenuItem = document.querySelector('#action-menu div[role="menuitemradio"]+div');
    if(deleteMenuItem.textContent.trim() !== 'Delete review') return console.error('wrong menu item', deleteMenuItem.textContent);
    deleteMenuItem.click();
    await sleep(300);
    
    // click the "yes I'm sure" button
    document.querySelector('div[aria-label="Delete this review?"] button+button').click();
    await sleep(2000);
    
    // check if there's any left, and do it all again
    if(document.querySelector('button[jsaction*="review.actionMenu"]:not([aria-hidden="true"])')) go();
  }
  go();
})()
