I can see 'Settings' -> 'Privacy' -> 'CLEAR BROWSING DATA', but that will clear my browsing info for all sites. I can also see under 'Settings' -> 'Site settings', there is an option to select 'All sites' and then pick a specific site. However, the site that has a cookie that I want to delete is not in that list (perhaps that list is only sites that have more than just cookies set?).
I also tried navigating to chrome://settings/cookies (which works in the desktop browser), but this doesn't work in the mobile browser.
