Here you go! Keep in mind, it’s a 1” bar, so you need 1” plates to work with it. 2” Olympic plates will not work.
Olympic bars are 45lbs. There are other types of bars in different lengths and weights. The standard barbell bar uses a 1” diameter bar vs. 2” of the Olympic bars and weighs between 12.5 and 15lbs. Fitbod has yet to add the ability to select which types of bars and plates you own, so it assumes you also have standard bars and not just Olympic bars.
For those weights, sure. As other noted though, you will soon graduate to heavier weights. A solid bar costs as little as $15 on Amazon and would double your capacity.
I use this standard bar with my plates from my adjustable dumbbells and it works perfectly: https://www.amazon.com/CAP-Barbell-Standard-Chrome-Bar/dp/B00497BM1G/ref=sr_1_4?dchild=1&keywords=cap+bar+standard&qid=1594528308&sr=8-4
