Using the Get-PnpSearchCrawlLog cmdlet wanted to filter the returned result set to a specific list. Before you begin, you’ll want to make sure you have access to the Crawl Log: https://yourSite-admin.sharepoint.com/_layouts/15/searchadmin/crawllogreadpermission.aspx

Connect-PnPOnline -Url "https://sharepointed.sharepoint.com/sites/food" -Credentials (Get-Credential)

$logs = Get-PnPSearchCrawlLog  -filter "https://sharepointed.sharepoint.com/sites/food/Lists/tacos/"

foreach($l in $logs)
{
    Write-Host "    "
    Write-Host $l.Url
    Write-Host $l.ItemId
    Write-Host $l.LogLevel
    Write-Host $l.CrawlTime
}

This will filter the returned results to a specific list. Note: when using Connect-PnPOnline I use my email address and App Password. App Password can be created/found here: https://account.activedirectory.windowsazure.com/AppPasswords.aspx
