Simple script (cloned from @ErickWendel) that accepts all friends in linkedin

accept-friend.js

// Run this in the devtools console, inside the linkedin friend request list
// Make sure to have all the requests displayed in the screen
// If something goes funky, increase the sleep time.

itens = []
document.querySelectorAll('.invitation-card__action-btn.artdeco-button--secondary').forEach(item => itens.push(item))

sleep = ms => new Promise(resolve => setTimeout(resolve, ms))
for (item of itens) {
    item.click()
    await sleep(500)
}
