Possible to make a software based receiver for wireless Keybord´s and mouse´s?

is there a possibility to make wireless mouse´s and keyboard´s usabal again without the receiver dongle?
In most cases i saw it is just a bluetooth receiver, so my assumption is that if my pc has bluetooth already i only need a kind of software.
And in cases when wifi 2,4ghz is used, i could use my wifi crd, or am i wrong?
Is it, if my assumptions are wrong, possible to use a esp32 or asp8266 instead of the dongle?
If there is a possibility to use the hardware although the dongle is missed, that would avoid a lot of trash.
Thanks
