Does zellij provide a command similar to tmux popup or an alternative?

[mainrs]

I want to show the output of a command inside a popup window of my zellij instance.

You mean like what's on the screencast page? https://zellij.dev/screencasts/

[mainrs]

Basically something that allows a script or similar to open some content as a pane inside the current zellij instance.

A possible scenario would be fuzzy searching. In a normal terminal I simply show the fuzzy search as normal (like a full page dialog that draws over the current content). But in the case of tmux or zellij, I want the fuzzy search dialog to display as a floating window on top of the panes.

tmux display-popup <shell-command> does this. It allows to show the content of <shell-command> inside a floating window.

When using the --generate-completion you also get the following shell functions defined - these provide shorthand versions of the above.
Below are examples for bash:

❯ zellij setup --generate-completion bash | grep -E 'z[a-z]+ \(\)'                                                                                             
function zr () { zellij run --name "$*" -- bash -ic "$*";}                                                                                                     
function zrf () { zellij run --name "$*" --floating -- bash -ic "$*";}                                                                                         
function zri () { zellij run --name "$*" --in-place -- bash -ic "$*";}
