it was neither a coup nor a coup attempt. i have a hard time fathoming the combination of ignorance and privilege that would lead a serious, thinking person to make this claim. at least the politicians grandstanding on the verge of tears are playing an angle.
what do you think would have happened if the rioters captured every single congressperson? what if they were all killed? if you think the answer to either of those questions is "the rioters assume control of any part of the federal government" then im not sure we have anything to discuss. killing congress doesnt, like, make you the new congress.
if you are calling it a coup because they WANTED to control the government (noting how ineffectual their attempt was), then you are making the word coup meaningless. you might as well call any whitehouse trespasser a coup.
context matters. they were political rioters, not a replacement government.
