Can I use my Lemmy account with Mastodon? - eviltoast

I signed up for an account on this Lemmy server as part of the recent migration from Reddit.

Based on my research about the Fediverse, I should be able to use my Lemmy account with Mastodon servers. However, I can’t seem to use my account with the Ice Cubes app. Is anyone else trying to do this or am I misunderstanding something? Maybe I should try another Mastodon client?

Otherwise, thank you in advance for the community’s help!
