I just posted an answer here, but don't see it. ??

The brand of toilet doesn't matter. You need a product that cuts calcium and lime. It may take some soaking and scrubbing. Once you get it clean, use the product regularly. CLR makes a line of products: https://clrbrands.com/en-US/Products/CLR-Household/CLR-Calcium-Lime-Rust-Remover

I don't know this specific tub, but here's the pictoral. The button (90105) should come out of its base, held by friction of O ring. This should allow you to disconnect the pressure line. If you are looking to replace the complete assembly, likely you will need a basin wrench to reach nut (65157). Here are links to Kohler, specific to this tub. https://www.us.kohler.com/us/catalog/svg_viewer.jsp?productId=415928&diagram=3 https://www.us.kohler.com/webassets/kpna/catalog/pdf/en/1010564_5.pdf

Smart-a$$ answer is to find an old 3 gallon pot in a salvage place. Best answer is to fiddle with the chain that goes from the handle to the flush flapper and see if adjusting its length makes a difference. If it's too short it might result in letting the flapper closing too soon and allowing your deposit to remain.

The jet that pushes the water through maybe clogged with calcium buildup.

There's something blocking it sometimes if you turn the water off in your home and turn it back on sometimes calcium from the pipes break loose and cause blockage in new style washerless valve assemblies.

Get a water hose,place in tub,connect to water outlet,turn on for a minute,then turn off.then disconnect hose,then water will come out.

Check the flapper and seat. Ensure that the flapper chain is not tight or caught underneath flapper. Check floor underneath tank for any sighs of water leaking or seeping from tank. tight tank to bowl nuts. good luck
