HRC may not have used the word "fraud", but she has been using some of the exact same terms that Trump has been using, like "stolen" and "shenanigans" :
“I was the candidate that they basically stole an election from,” Clinton said Monday on the New York Times podcast “Sway.”
“I was the candidate who won nearly three million more votes. So no matter how they cut it, it wasn’t the kind of win that people said, ‘OK, it wasn’t my candidate, but OK.’ This election is still front and center in people’s psyches. And people fight about it every day online, because there is a deep sense of unfairness and just dismissiveness toward his victory, and he knows it,” Clinton said.
Clinton blamed her loss in certain key states on former FBI Director James Comey’s letter Congress announcing the existence of emails under investigation. “I absolutely thought I was going to win. So did everybody else. I mean, I know people look back now and say, well, it wasn’t — we were going to win. We were absolutely going to win.”
Her election loss, Clinton complained, was partially due to a disinformation campaign stemming from “vast right-wing conspiracy.”
“There were academic studies done afterward, lots of them, about why people ended up not voting for me, and it was shocking what they believed. I mean, the disinformation was incredibly pervasive,” Clinton said.

And then there's this:
"There was a widespread understanding that this election [in 2016] was not on the level,” Clinton said during an interview for the latest episode of The Atlantic’s politics podcast, The Ticket. “We still don’t know what really happened.”
“There’s just a lot that I think will be revealed. History will discover,” the Democratic Party’s 2016 presidential nominee continued. “But you don’t win by 3 million votes and have all this other shenanigans and stuff going on and not come away with an idea like, ‘Whoa, something’s not right here.’ That was a deep sense of unease.”
In August, Clinton said Democratic presidential nominee Joe Biden should not concede the upcoming November election “under any circumstances” because she believes “this is going to drag out, and eventually I do believe he will win if we don’t give an inch, and if we are as focused and relentless as the other side is.”

HRC is essentially saying that should Biden have lost, that he should be doing exactly the same thing that Trump is doing now. I don't think using her as an example helps your case.
