Sucuri Blocking Ahrefs Bot

I use Ahrefs for Site Audit and it told me that Sucuri might be blocking Ahrefs bot and that’s why the site audit isn’t been done properly. I use the free plan and I would like to Whitelist the Ip Addresses that Ahrefs Bot uses. I don’t want to upgrade to the paid plan. What do i do?
