How to use resume token string as input for resumeAfter ?

Hey I am trying to resume a changestream using the token. When I provide the token in the resumeAfter argument, I am getting type mismatch error.

What did I try ?

token = "gl3SitAAAAAFRjxfaWQAPEQ43XRIYXprUUpFTUJxODVTeHZRAABaEARfzWwPy21FhLM0HGgXxs1aBA=="

token =

{"_data": bson.binary.Binary(token.encode())}

when i pass this token as input to resumeAfter in the db["collection"].watch() function i am getting an type mismatch error (`a bytes-like object is required, not 'dict'`
). Couldn't find any documentation around this in the official site. Will be helpful if this is added to the documentation
