Mission Control has a delay to display the Desktop Preview

Describe the bug
I am testing BTT to get the Desktop Preview
But there is a very annoying delay(one or two seconds) to display the Desktop Preview using the "Mission Control & Immediately Show Desktop Preview". It is disturbing. I wonder if this bug can be solved. Tanks for informations.

Affected input device (e.g. MacBook Trackpad, Magic Mouse/Trackpad, Touch Bar, etc.):
Mac mini M1 latest MacOS

unfortunately this can not be resolved, without the delay the previews can not be shown

@eole it works quickly for me.

I perform the action using the BTT AppleScript and Keyboard Maestro.

I am running current version of macOS Big Sur and macOS Monterey

Thank you Andreas, I will then stick to the basic setting : 16 space on MacBook Air and 38 spaces(!) on large 32" screen. With these settings for each screen Mac open automatically the previews. On large screen I must say it is quite a pain to set such a number of spaces. I will get used to until Mac reduce the number of spaces needed for the effect that we need.
