Which "family" do I put in my data using brm function?

Question

I have a dataset for a logistic regression in brm. My data consists in a column of presence of visual display in frogs and the second column describes their activity period (0=night, 1=day, 2=both). Below, an example of my dataset:

visdisp activity
0       0
0       1
1       2
0       2
1       0
1       1

Using brm, there is the "family" argument. My model is visdisp ~ activity I am not sure what to put in this item. Could someone help me? Thanks in advance.
