Bothans in canon?

I know Bothans appeared frequently in Legened and were pretty well defined as a civilization, but has any information about them been revealed in canon?

Are they still fur covered mammalians or are they something else completely? 😕

I think in canon they were only mentioned in Rotj by Mon mothma

They were briefly mentioned in Bloodline:

The numerous citizens of various worlds milled around, both on the mobile sidewalks and around them: a group of Bothans growling to one another in front of one office's door, a Gungan having an animated conversation via the comlink in his hand, and two Wookiees far ahead of her on the sidewalk, being propelled forward past the throngs of politicians, workers, lobbyists, and visiting constituents that perpetually filled the complex.

But yeah... I think that's about it in canon.
