Anything happens when I install the promt translation sdl plugin, it does not appear on the using drop down list of the tm provider neither on the all language pairs or on a single one

Anything happens when I install the promt translation sdl plugin on sdl trados 2021, it does not appear on the using drop down list of the tm provider neither on the all language pairs or on a single one. is it a fault of SDL Trados or it is a fault of promt russian tm provider?

Can anybody of you help me to solve this?

Thanks in advance.
