Micromamba cannot be activated in shell scripts

[Missthepast]

Hello, may I ask how to activate micromamba installed using the official installation method in a shell script.Using absolute path activation in shell scripts also generates errors. Here are the methods I have tried.

It can be initialized correctly, but cannot activate using source.

I am using Docker and Ubuntu environment.
Is there any way to solve this problem? Use micromamba in the shell script to activate the specified environment. Currently, I only have micromamba in my environment.
