Help bleeding front brake

[Jordanto]

Hello everyone. I’m very new to cycling and have made my first purchase. A mongoose hybrid style bike with hydraulic brakes.
Upon assembly it looks as if my front brakes don’t work at all and maybe there was a leak or air in the lines.
I’m wondering if anyone can help pointing out which screws to loosen for bleeding this set.
Moogoose Reform Sport 700c Hybrid
Shimano Br m315 (I believe)
Only basic assembly instructions came with the bike

thank you in advance

You will need some hydraulic brake mineral oil and a bleed kit and some torx bits

One note of caution is I struggled to bleed my last set and long story short the seal on the caliper had blown. Just worth keeping in mind as a possible reason you have lost pressure in your brakes.
