Multilingual Keyboard App for Android

I’ve been looking for a while for one that supports more than 4 languages at once, but it seems hard. Of course the default one only supports up to 4. If I google for it I only find the lists of the “best” app, listing features like emojis or themes but no mention of how many languages at once they support. I remember using one in the past and I think it only allowed for two.
Did anybody have any luck?

I’ve been using SwiftKey for a number of years. Sadly, they only support 5 languages. While that isn’t a whole lot better, it’s at least one more. And at least you can easily turn them on/off (which is what I’m doing all the time).

Oh yeah, I was aiming for at least 7 sadly, but thanks.
I’ll look it up anyway.
