In an interview, Ms. Trump said she planned to continue talking about work force development at home, as part of a campaign message that will help her father. She is seen by campaign officials as one of the top fund-raisers and surrogates for the re-election campaign, though she said, “I’ve always bristled at the term surrogate,” which she said suggested merely “talking about things I haven’t been involved in.”

Her draw comes in large part because of her high name recognition across the United States, aides said, and her potential to sway the critical voting block of suburban women with a message about newly enacted benefits that she championed. In the White House, she pushed successfully for an expanded child tax credit — though much of the benefit goes to well-to-do families — and paid family leave for federal workers.

“I do think we have a lot of wins on the board the American people don’t know about,” she said.

Ms. Trump, however, views herself less as a political voice like her brother Donald Trump, Jr., and more as someone who can mobilize voters and help her father through a focus on two issues the Democrats claim as their own: women’s empowerment and the American work force.

She said that she would “continue to be focused on the areas where I’ve helped the president move the ball. I gave up my life to move to Washington to try to help Americans, and I’m proud of what we’ve been able to accomplish.”

Ms. Trump has become a fixture at major international gatherings since she raised hackles at her first one in 2017, when she briefly took her father’s chair at a Group of 20 summit meeting in Hamburg, Germany.

Prime Minister Shinzo Abe of Japan invited her to the Group of 20 meeting last July in Osaka, where she gave a keynote address on women’s empowerment, and then delivered a video report on Mr. Trump’s dealings with foreign leaders. A brief video from a private gathering, showing her awkward foray into a conversation with the leaders of France, Britain, Canada and the International Monetary Fund, quickly went viral and fed criticism that she was out of her depth.
