Switch between animation in Blender

[Kino-san]

Thank you! I feel very stupid, it works perfectly :') I was very confused because the "dope sheet" was completely empty, even though the animation was running and working (added a screenshot to illustrate my point), and I thought it had to be resolved there. I thought I already had checked the NLA editor but well, looks like I didn't...
   
Thank you very much! It helped me greatly
