Question about dataset for GRU network, future sequance prediction

I want to build model that predicts for 12 timestamps in the future movement of the graph.

But I am new in GRU network using.
Can someone who already used GRU give me an advise. What data is better to use with features or just single one input static data.

Excample Dataset with features:

feature1, feature2, feature3,
77.01, 77.68, 78.91
etc.

Excample Dataset without features:

data
77.91
76.12
etc.
