There is a recent upward trend in transaction count for USDC/USDT (both native and ".e" bridged tokens) since a daily low on 3-5-23

Tx share seems to be falling for ".e" bridged tokens, but this appears to be due to growth in native token transactions instead of decreasing transactions in ".e" bridged tokens.

The #1 project in both sending and receiving transactions of USDC/USDT appears to be Stargate Finance, which has grown in tx volume among projects to ~20% share, at the start of the trend it accounted for less than 1% tx share.
