How to set a variable into bp_character animation?

I have a boolean variable into Bp-character animation (in event graph) and I need to set it from level blueprint. I tryed wiht “cast to bp_animation” but don’t know what connect to “object”.
May be there are other ways to access.

Google is full of comments saying “set your variable public”, “use cast to…” use blueprint interface…" but it is sad when I follow tutorials for get or set variables between blueprints and always the same error: “BP_animations does no inherit…” This should be easier, more direct. I know I am part of the problem because my knowledge is still limited but sharing variables between blueprints cannot be so twisted.

Are you talking about the animation blueprint? Is it the player?
