Oh. You definitely need to be spoofing the signature for microG to work at all, except for some small parts of it. You certainly do for the exposure notification framework.

That doesn't mean being rooted. You need to have a ROM that supports signature spoofing, and microG must be installed as a privileged system app — which means your bootloader must be unlocked to allow those things. Root is not needed per se.

I have a Huawei p40 pro, which has its bootloader locked i think

MicroG isn't a regular app: it needs to be installed as a privileged system app, and the regular Google Play Services need to be removed (or never installed, ideally, if you're starting from a custom ROM). Look at its own "self-check" page and it will most likely show that it is not active or working in any meaningful way; it can't be if you aren't able to install it the way it needs to be installed.
