Is there a method/tool that has the ability to search Mastodon for the most liked posts (in the last 24 hrs) with a specific hashtag?

Not that I'm aware of (would love to hear about it if I'm wrong though!). It could be a feature request for something like Fediverse Explorer, maybe?

On Lemmy you can sort by top day in a community, idk if you can open up mastodon hashtags through Lemmy or not
