Jupyter notebook not trusted

I am using Anaconda to work on a Jupyter notebook which displays "Not Trusted" (see on screenshot below). What does it mean? Is it a problem? How can I solve it?
It is a security feature to disable the execution of arbitrary code from untrusted notebooks, without the user's consent. There is a doc page about it: https://jupyter-server.readthedocs.io/en/stable/operators/security.html#security-in-notebook-documents It won't prevent you from manually running the code, that's actually one way of "trusting" the outputs.
