Slow play; pulling teeth. Need a time bank.
There is a player on at the moment who runs the clock down for every decision. Clearly just parks there clicking the 'sit back in' button. Tedious. Lots of angry faces and players not sticking around.
You need less than a quarter of the given time usually, so 3 quarters of it could be time bank, recharged at a rate of 1s per hand, something like that. Though under the gun position needs a bit more time after dealing since time starts before they get to see their cards (unless you fix this). Alternative solution; to kick them after being made to sit out 3 times and lock them out of the table for an hour.
Separate note, lose the clown face emoji. Rule: "Do not shame players for how they bet". Your own bots are breaking this rule and the clown emoji is only ever going to be toxic.
