How do I use gaia for our local protein sequence annotation?

Hi,
This is a simple straight forward question.
I am trying to use gaia but didn't find any tutorial or proper documentation.
My case is simple, I have thousands of un-annotated or poorly annotated metagenomics originated protein sequences. I want to annotate using gaia. How do I achieve it? Do I need to train my own or can I use gLM2_embed model?
Please let me know

Thanks in advance,
Tulasi
