It actually lists far more than three mechanisms and mentions "Level 3: Action as an Ionophore" but maliciously does not name zinc by name.
I think that blocking the importer molecules is the by far most important effect of ivermectin because the virus has no chance if it cannot block the gene expression needed to produce the self-defence stuff.
Ivermectin also plays a role in regulating the immune-response, avoiding or dampen the cytokine storm. This is why ivermectin also helps in the ICU, when the virus load is already going down.
