What evidence supports the Trump-Carlson dispute claim?

Trump's Truth Social attack on Carlson, Marjorie Taylor Greene and Thomas Massie doesn't include any corroborating detail about the alleged meeting between the three, and the report notes this claim lacks supporting evidence [1]. The post is described as Trump calling them "losers" and criticising Carlson's audience and political prospects, but no independent confirmation of the meeting itself is offered [1]. I don't have further coverage that substantiates the dispute claim beyond this.
