publishing shiny app with flex dashboard on in R doesn't work

I made a shiny flex_dashboard markdown report and I want to publish it on but my account is not added

I clicked on Posit Cloud

put my token

and my accound isn't added

I tried another token and another account but the problem is same. and I tried to publish on RPubs but it seems it should be a knitted HTML file

WHAT IS THE SOLUTION what should I do to publish it
