Self assesment threshold - £100k -> £150k

I was alerted by HMRC that I no longer needed to file a self assesment tax return as of May 2023 as my income is above £100k but falls below the new £150k threshold. How does HMRC collect tax owed due to the erosion of the personal allowance for earnings over £100k? I am not sure if I owe tax for the 23/24 tax year (the year in which i no longer needed to submit a self assesment) and haven't recieved any communication from HMRC. Thank you

Thank you for the reply, but I’m not sure that link answers my question. If I’m not required to do self assessment, how would I pay tax for any earnings over £100k that may not have been captured through PAYE?
