How to wait for a value to be written to the session?

Question

Laravel

Good afternoon! I wonder how to wait for the result to be written to the session and only then perform some actions. Session at me is stored in a radish. And the problem is that the recording does not happen instantly, but after a while. And the following code will simply not take the value of the session because it has not yet signed up. As it is possible to make less curve option, for catching of record, callback. I did not find anything similar in the docs.
