problemas al querer integrar shader en minecraft bedrock edition

in the latest version of bedrock edition it does not allow me to install any shader externally to improve the experience I have migrated from the java edition version and I have used very demanding shaders in that version but in bedrock every time I look for a shader and install it and try to test the game it stays normal there are times that some things bug even if I look for the shaders for the latest version but it does not make sense because as I have already told you in java I have used very demanding shaders and it goes at 40 fps my computer is a 10th generation i5 with two 8 gb ddr4 ran modules but the bedrock does not let me install or even test although the shader is very light the one I try to install is not applied in any way in my worlds I would like you to solve that I am migrating from java to bedrock to be only in the bedrock version and this is discouraging me a lot not having the shaders like the one I used from java which changes the experience a lot when play I wait for your response
